Abstract :
An inverse analysis based on a modified Kalman filter algorithm (KFA) was carried out to identify mode-I parameters of a cohesive zone model (CZM) for simulating solder interfacial failure in electronic packaging components. The exponential cohesive law was investigated here and its cohesive parameters were determined in two steps by approaching the finite element simulation results to the experimental information. The simulation result based on the identified CZM parameters shows that the present inverse procedure is effective and promising to identify the exponential types of CZM parameters.
