• Damage predictions for the 2024-T351 aluminium alloy under both monotonic and cyclic loadings

  Journal of Physics Conference Series · 2025-06-01

  articleOpen access

  Abstract The failure behaviour is investigated for the 2024-T351 aluminium alloy subjected to monotonic and cyclic loading conditions using the void growth model. Notched cylindrical specimens are employed to analyse the behaviour under monotonic loading, while smooth cylindrical specimens are used for cyclic loading. The analysis encompasses a broad spectrum, ranging from the ultra-low cycle fatigue regime to the low-cycle fatigue. This comprehensive approach aims to provide a thorough understanding of fracture behaviour across a wide range of loading severities.

• Lived Experience of Black/Global Majority Disabled Pupils and their Families in Mainstream Education

  Explore Bristol Research · 2024-03-01

  bookOpen access

  This research is about the lived experiences of Black/Global Majority Disabled pupils, aged 11-16 and their parents about schooling. It explores experiences of mainstream school placement, participation, support and attitudes of school staff. <br/>The research found that there is inadequate support for Black/Global Majority Disabled pupils and their families in terms of advocacy, peer support to share information and provide clarity on entitlement, help to empower them and protect children’s right to mainstream education. <br/> <br/>Children and young people told us that they would like; <br/>• To have better choice and control over their support, so as to be better able to join in and participate in the range of school activities and opportunities.<br/>• An end to the separation of Black/Global Majority Disabled pupils and recognition of their proud intersectional experiences, not ones based on deficit. <br/>• To have a say in writing school rules and policy, to coproduce practise and build a sense of belonging.<br/><br/>Parents highlighted their concerns to us in terms of; <br/>• That they feel they have little support and limited or no choice about where and how their children are educated.<br/>• An excessive use of disciplinary procedures and practices of surveillance towards Disabled pupils and Black children that result in negative consequences or exclusion. <br/>• Difficulties navigating an education system that is complex and often overlooks intersectional experiences of disability and race.<br/> <br/>The current lack of support makes it hard to address any tensions around the intersections between disability and race when navigating the education system. To address these issues, we make the following six recommendations. <br/><br/>Recommendations:<br/>• Improve understanding and recognition of intersectional experiences. Increase the representation of Black/Global Majority Disabled pupils within the education setting and social justice work.<br/>• Tackle the trauma experienced through grouping and separation. Encourage work in schools to address the effects and trauma caused by segregation on all pupils. Promote independence, choice and control in EHCPs. <br/>Develop advocacy support to ensure EHCPs achieve independent living and human rights of Black/Global Majority Disabled pupils.<br/>• Challenge negative attitudes and promote positive representation. Diversify the teaching workforce, profile more diverse experiences in school and promote learning about intersections of disability and racial justice. <br/>• Expose harmful disciplinary procedures and surveillance. Build a campaign between disability and racial justice organisations to highlight and end disciplinary procedures that lead to exclusion and discrimination of young people.<br/>• Challenge segregation, promote participation. Highlight school intake discriminatory practices affecting Black/Global Majority Disabled pupils, showcase practical and applied solutions that demonstrate how inclusive education can and does work elsewhere

• A Novel in Situ Miniature Creep Tester for Evaluation of New Cladding Alloys

  Advances in materials technology for fossil power plants : · 2024-10-10 · 2 citations

  articleOpen accessSenior author

  Abstract Miniature specimen tests are necessary to assess the mechanical properties of new fuel cladding alloys for next-generation nuclear reactors. The small specimen allows for extensive testing programs from limited volumes of material. However, there is a lack of testing equipment to perform high-temperature mechanical tests on the miniature specimen. This work presents the development of a high-temperature creep test system for miniature specimens with in situ scanning electron microscope (SEM) testing capability for real-time characterization. Here, we discuss the challenges of the development of the system, such as gripping the samples, loading, heating, cooling mechanisms, and strain measurement. The equipment is used to investigate the creep behavior of FeCrAl alloy Kanthal APMT, and the results are compared with conventional creep test data from the same batch of this material.

• Critical Evaluation of a Novel Analysis Technique for Assessment of Printed Circuit Heat Exchangers in High-Temperature Nuclear Service

  Journal of Pressure Vessel Technology · 2023-03-10

  articleOpen accessSenior author

  Abstract Application of printed circuit heat exchangers (PCHEs) to very high-temperature reactors (VHTRs) requires mechanical performance assessment methodologies. The PCHE morphology consists of thousands of millimeter-scale channels, for enhanced thermal efficiency, enclosed in a meter-scale PCHE core. PCHE geometry under thermomechanical creep-fatigue transients results in multi-axial interactions between its different segments, such as channeled core, walls, and headers. These global-level interactions influence the local channel-level responses. Hence, developing a PCHE performance assessment methodology, following the ASME Code, Section III, Division 5 provisions, is a critical gap to be filled. There is no analysis or design methodology available in ASME Code to assess a PCHE for its global and local level performances under high temperature and pressure loadings. This paper critically evaluates a recently proposed two-step analysis technique to estimate global interactions and local channel-level responses of PCHEs. In this novel analysis technique, the channeled PCHE core is replaced with orthotropic solid blocks of representative stiffness properties for the global thermomechanical analysis. Subsequent channel scale submodel analysis with detailed channel geometry, loading, and elastic-perfectly plastic (EPP) material model estimates the local responses for PCHE performance assessment. This paper critically evaluates this novel technique for its effectiveness in PCHE performance assessment. Finite element (FE) models imitating various analysis issues are developed, and FE analysis results are scrutinized. An important outcome of this study is the validation of the novel two-step PCHE analysis technique for application to the performance assessment of PCHEs in VHTRs.

• Influence of Weld Sequence on the Low-Cycle Fatigue Failure of WUF-B Connections

  Journal of Structural Engineering · 2022-04-19 · 2 citations

  article1st authorCorresponding

  Experiments on post-Northridge welded unreinforced flange bolted web (WUF-B) connections demonstrated a new low-cycle fatigue (LCF) crack initiation mechanism with final rupture occurring either near the weld access hole or the weld regions. Post-Northridge connection research reports and related commentary indicated that the weld and heat-affected zone (HAZ) conditions might be contributing factors in LCF-initiated failures of the modified WUF-B connections. The experimental study reported herein investigated the influence of weld sequence on the fatigue failure of the WUF-B connections. Two exterior WUF-B connections were fabricated using different weld sequences in laying the complete joint penetration welding between the beam and column flanges. These connections were tested under a constant-amplitude displacement-controlled loading protocol until crack initiation. Both specimens failed by cracking at the weld access hole, one in a brittle manner and the other in a ductile manner. Analysis of the recorded data demonstrated the influence of weld sequence on strain responses at the weld toe and weld access hole regions. Accumulation of strain with cycles, which is a phenomenon known as strain ratcheting, was observed near these locations in both tests. Recorded strain responses near the crack locations indicated the cause of earlier failure of one specimen compared with the other. Finally, future research needs in mitigating the influence of welding sequence on fatigue failure of welded steel moment connections are discussed.
