DOI: 10.1016/j.ijimpeng.2017.02.024
Abstract: The objective of the present work is to compare two different models aiming at numerically reproducing Adiabatic Shear Banding (ASB) assisted failure. ASB is herein considered as a deterioration mechanism whose consequences in the material… read more here.

DOI: 10.1016/j.jeurceramsoc.2021.06.038
Abstract: Abstract The residual-stress induced failure of Ti-6Al-4V/Si3N4 joints brazed with two different Si3N4 ceramics possessing different intrinsic properties was elucidated through experimental and finite-element (FE) thermo-mechanical simulations incorporating the local elasto-plastic properties of the as-received… read more here.

DOI: 10.1063/1.4975348
Abstract: The electric current exponent, typically with j−n form, is a key parameter to predict electromigration-induced failure lifetime. It is experimentally observed that the current exponent depends on different damage mechanisms. In the current research, the… read more here.

Abstract: Catastrophic failure of diode pumps in laser systems exhibiting back-irradiance is a common occurrence yet poorly understood. Prior paper has established boundaries for time-zero failures, but these results cannot be used to deduce safe back-irradiance… read more here.

DOI: 10.3390/mi13060953
Abstract: The development of advanced electronic devices leads to highly miniaturized interconnect circuits (ICs), which significantly increases the electromigration (EM) phenomenon of solder and circuits due to higher current density. The electromigration of solder joints under… read more here.
