TWI applied numerical modelling and optimisation procedures With its focus on joining processes, particularly welding, structural integrity of materials, joints and structures, TWI has developed and applied numerical modelling and optimisation procedures such as finite element analyses for over 30 years. 

TWI has a team of qualified engineers and analysts who provide expertise in:

  • Fracture mechanics
  • Weld modelling
  • Computer aided fatigue design
  • Engineering Critical Assessments using finite element analysis
  • Residual stresses and their effects
  • Weld distortion prediction and control
  • Modelling of guided waves for inspection•
  • Post weld heat treatment
  • Friction stir welding simulation
  • Micro-mechanical approach to damage modelling
  • Plasticity and creep
  • Structural dynamics
  • Thermal analyses and local approach methods
