Objective To assess Multi-directional Impact Protection System (MIPS) helmet technology on rotational velocity during head impact using a novel testing method. Design Optimization study. Setting ...

Measuring how materials respond to different deformation speeds is imperfect, leaving gaps and uncertainties across strain rates. A single, self-consistent method to measure hardness across 11 orders ...

In my January 2024 column, I reported on a new ASTM test method for use in assessing the damage tolerance of sandwich composites under compression loading: the sandwich compression-after-impact (CAI) ...
