Performance metric | Advantages | Disadvantages |
---|---|---|
Displacement field | - Can be used even with linear fe analyses - Simple to use and interpret - Quantitative | - Does not provide a pertinent information on the crack extent and potential failure mechanisms |
Damage pattern | - Can be used to detect potential failure mechanisms - Suitable for nonlinear fe analyses | - Nonlinear FE expertise required - Expert engineering judgement is required to detect potential failure mechanisms - A well refined mesh and a validated constitutive model are required |
New suggested TCW metric | - Suitable for nonlinear fe analyses - Quantitative - Can be used at local or global scale of facility | - Nonlinear FE expertise required - Can give information on potential failure mechanisms but expert judgement is still required |
