ABOUT WORKSHOP
This workshop introduces theoretical fracture mechanics covering LEFM approach with dynamics of crack initiation, propagation, and failure. Workshop also explains factor in predicting the Stress Intensity Factor (SIF); Consideration of crack geometries, crack growth laws, time, cycle, dependent combined with time, temperature dependent crack growth; Fatigue life calculation under simple, non-proportional, transient, spectrum, hold, combination and load schedules, further fatigue life, SIF history life calculation. Workshop will be a hybrid studies of fracture mechanics theory and 3D Crack Growth Simulations / computational fracture mechanics with hands on experience. Users are encouraged to bring their problem statements (with FEA) performed and experts will guide to simulate the fracture studies during the workshop.
