As today's electronics systems continue to shrink and become more complex and pervasive, failures can cause costly downtime, product delays and recalls, and debilitating reputational damage. Finding and fixing failures before they do damage is important, but becomes increasingly challenging when devices are built using ever more complex designs. The solution is to employ a comprehensive, multidisciplinary approach to electronic system failure analysis. In addition, many failures can be avoided altogether by thorough testing, coupled with the latest focused ion beam circuit edit techniques. These advanced methods quickly and inexpensively debug and validate design fixes or explore design optimization opportunities in integrated circuits without having to commit to costly and time-consuming full mask spins.

Finite element representations of crash test dummies are widely used in the simulation of vehicle safety systems. The biofidelity of such models is strongly dependent on the accurate representation of the nonlinear behavior of constituent rubber, plastic, and foam materials. This article presents a simulation workflow in which material parameters are more easily optimized and demonstrates its use in the calibration of a viscoelastic model for the behavior of rubber-like materials in a side-impact dummy.

Researchers at MIT have evaluated a wide range of helmet liner designs and materials for potential use in the U.S. Army's advanced combat helmet (ACH). To measure the effectiveness of candidate materials, the investigators rely on finite-element simulations that are validated by shock tube testing at Purdue University. Of the various filler materials examined, glass beads, glycerin, and water show the most promise for blast attenuation.
