... constitutive model creep SnAg lead-free solder Lead-free solders such as SnAg and SnAgCu are used extensively as replacements of SnPb solders in microelectronics packaging. It has been found that, in comparison with traditional SnPb eutectic solders, these lead-free solders have much higher melting...

...Gang Chen; Xu Chen; Kwang Soo Kim; Mohammad Abdel-Karim; Masao Sakane A series of multiaxial ratcheting tests were conducted on 63Sn–37Pb solder. A unified viscoplastic constitutive model was developed on the basis of the Ohno–Wang kinematic hardening model, and the rate dependence of the material...

...Xianjie Yang; Yan Luo; Qing Gao Based on the time dependent multiaxial deformation behavior of 96.5 Sn - 3.5 Ag solder alloy, a constitutive model is proposed which considers the nonproportional multiaxial cyclic deformation properties. In the back stress evolution equations of this model...
