Explainable Safety and Security (EXSS) is concerned with investigating approaches to explainable AI (XAI) that will enable the accelerated use of AI/ML functions at the edge for robotics safety functions, and that can potentially address cybersecurity weaknesses related to deep networks. Advances in these areas will be highly valuable for the robotics and automation market.

The continued safe operation of critical infrastructure is key in ensuring economic prosperity. The drive towards carbon neutrality presents significant challenges to engineers as increasing operational efficiency often results in harsh, unfavourable operating conditions (e.g. offshore wind turbines). The cost of implementing more efficient processes is a reduction in materials performance resulting in prohibitively short component lifetimes. The challenge facing engineers lies in improving the… Show more The continued safe operation of critical infrastructure is key in ensuring economic prosperity. The drive towards carbon neutrality presents significant challenges to engineers as increasing operational efficiency often results in harsh, unfavourable operating conditions (e.g. offshore wind turbines). The cost of implementing more efficient processes is a reduction in materials performance resulting in prohibitively short component lifetimes. The challenge facing engineers lies in improving the structural integrity assessment (SIA) methods. Current SIA methods are predominately stress-based and thus, inherently dominated by the yield strength of the component material. Non-linear materials such as steels typically fail by strain induced plasticity where significant additional energies are adsorbed prior to fracture. Strain-based assessments contain considerable built in conservatisms that have not yet been explored. The principal aims of this fellowship application are to develop more advanced SIA methods by considering conservatisms in existing stress-based and strain-based approaches and to exploit recent advances in machine learning to identify and predict key parameters influencing transformative damage in fracture toughness testing. The fundamental understanding of material damage generated in this work will reduce knowledge gaps currently impeding SIA improvement. The benefits of this work include advances to multiple international codes and standards, the continued safe operation of aging critical infrastructure, longer more realistic estimated lifetimes for new components and, significant industrial cost savings through enhanced component design, reduced maintenance cost and reduction in early structure retirement.

British Standard BS5500 appendix D was developed to provide design rules to prevent the catastrophic fracture of pressurised components. Although partly developed from working practices, the rules were validated from large scale test results and the use of fracture mechanics in 1998. With the introduction of the Euro Norm EN 13445, the BS rules have remained extant, however, although the original EN rules were strongly based on the BS approach, significant changes were introduced after… Show more British Standard BS5500 appendix D was developed to provide design rules to prevent the catastrophic fracture of pressurised components. Although partly developed from working practices, the rules were validated from large scale test results and the use of fracture mechanics in 1998. With the introduction of the Euro Norm EN 13445, the BS rules have remained extant, however, although the original EN rules were strongly based on the BS approach, significant changes were introduced after theoretical assessments in 2004. These have recently been analysed using the latest fracture mechanics approaches and assessed against validation tests and published failures and found to be potentially unsafe.The setting up of a collaboration group will facilitate members of this group being co-opted on to BSI PVE/1/18 to develop proposals to the CEN TC54 WG B to address potential concerns associated with EN 13445 Annex B.The Nuclear industry also uses sophisticated versions of fracture mechanics approaches to derive its safety cases. However large conservatisms are generally introduced which may result in barriers to the introduction of new materials and over reliance on inspection.The intention of this project is to bring together the approaches used in the Nuclear industry with a reassessment of the treatments adopted by the Pressure Vessel codes to propose an optimised approach for the safe design of Pressurised components.The outcome of the project will propose optimised procedures for Pressure vessels and piping for safety critical applications and provide the basis for an update to the National and International Pressure Vessel Standards.
