Damage mechanics of electromigration induced failure
Cemal Basaran,Minghui Lin +1 more
TL;DR: In this paper, a new damage mechanics formulation is implemented in a general finite element procedure and used for simulation of solder joints electromigration induced failure, where nonlinear viscoplastic time-dependent nature of the material and current crowding effects are taken into account in the formulation.

Mechanothermodynamic Entropy and Analysis of Damage State of Complex Systems
TL;DR: An attempt to propose a generalized theory of evolution which is based on the concept of tribo-fatigue entropy, which is determined by the processes of damageability conditioned by thermodynamic and mechanical effects causing to the change of states of any systems.

Constitutive equations for cyclic plasticity and cyclic viscoplasticity
TL;DR: In this paper, the cyclic constitutive equations developed and used at ONERA and LMT-Cachan are presented in detail in terms of a hierarchy of various models, including the Ohno-Kachi time-independent plasticity theory, two unified viscoplastic models by Walker and by Krempl and Yao, the new developments of the endochronic theory by Watanabe and Atluri.
