Validation of different SAC305 material models calibrated on isothermal tests using in-situ TMF measurement of thermally induced shear load

Finally, for Sn96.5Ag3.0Cu0.5 solder alloy the ability of the different material formulations to reproduce trends of measured force-displacement hysteresis was analyzed: for double power-law creep model (DPL), unified inelastic strain formulation by Anand, and unified visco-plastic model proposed by Chaboche. Their accuracies in predicting of the acceleration factor between the different temperature profiles are summarized and discussed.
