Transient-Dynamics of Microcircuits and MEMS in Shock and Vibration

ShockVibPix

Synopsis

Micro-circuits and Micro-electromechanical systems are subject to accidental drop, shock-impact, large velocity deformation, and shock due to nearby impact in portable electronic applications. Damage initiation and progression in materials and interfaces, methodologies for survivability-prediction are not well understood. Applications being studied include – cellular phones, PDAs, notebook computers, missiles, tanks and unmanned airborne vehicles.
