Structural Integrity

Structural Integrity addresses the fitness for purpose of mechanical structural components and assemblies that are capable of withstanding specific loading configurations during their life cycle. Research focuses on:

  • Design code assessments for fusion reactors including EN13445, ASME Section VIII Division 2, ASME Section III, RCC-MRx.
  • computational methods for limit load analysis, elastic shakedown loads and buckling loads of aerospace, civil and marine structures
  • prediction of inherent residual stresses and distortions due to advanced joining and welding technologies such as friction stir welding
  • high and low cycle fatigue of structural components including creep fatigue interaction.
  • thermo-mechanical response of various materials subject to specific loading configurations such as particle beam impacts.
  • dynamic and thermo-mechanical response of Micro Electro Mechanical Systems (MEMS).
  • structural response of glass-fibre reinforced composite pipes and pressure vessels through experimental and numerical assessment.
  • progressive failure damage mechanics modelling and testing of fibre reinforced composite materials.
  • modal analysis of composite materials and other structural elements.
