TL;DR: In this article, a thermodynamic framework has been presented for damage mechanics of solid materials, where entropy production is used as the sole measure of damage evolution in the system, and predictions are compared with experimental results, which indicates that entropy production can be used as a damage evolution metric.

TL;DR: In this article, a micromechanical model for effective elastic properties of particle filled acrylic composites with imperfect interfacial bonds is proposed, where the constituents are treated as three distinct phases, consisting of agglomerate of particles, bulk matrix and interfacial transition zone around the aggregates.

TL;DR: In this article, a micro-mechanical damage model is proposed to predict the overall viscoplastic behavior and damage evolution in a particle filled polymer matrix composite, which consists of polymer matrix, particle fillers, and an interfacial transition interphase around the filler particles.

TL;DR: In this article, the authors evaluated the damage mechanism in solder joints in electronic packaging under thermal fatigue loading and showed that damage mechanism under thermal cycling and mechanical cycling are very different, and they also showed that thermal fatigue and isothermal mechanical fatigue are completely different damage mechanism for microstructurally evolving materials.

TL;DR: In this article, high, moderate, and low levels of interfacial adhesion between the matrix and the filler are investigated, while all the other material properties are kept constant, including elastic modulus degradation, load-drop parameter, and plastic strain range.
