Abstract

It is important that evaluations of thermal fatigue life of the lead-free solder joints under temperature changes are performed accurately. In the estimation of the fatigue life of the lead-free solder joints, we have to get accurate low cycle fatigue properties of the solder. Inelastic strain range by low cycle fatigue test using small shearing test pieces is generally acquired by FEA. However, acquisition of inelastic strain range by FEM isn't verified that acquire the correct data by this way. I do acquisition of inelastic strain range by low cycle fatigue test using small shearing test pieces and FEM by same condition. Through comparing that data, acquiring inelastic strain range by FEM will be judged its validity.
