Adaptive Twisting Metamaterials
Advanced Materials, Volume 38, Issue 21, 13 April 2026.This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

A measurement of wave propagation in the split Hopkinson pressure bar
Measurement Science and Technology, 2009 This paper presents results from optical and analytical measurements of stress wave propagation in a rod of PMMA. The rod is loaded between the incident and transmitter bars of a split Hopkinson pressure bar. Displacements in the rod are measured using high speed photography with digital image correlation.

Numerical Simulation for Bar Straightness Effect in Split Hopkinson Pressure Bar
Procedia Engineering, 2017 Abstract Bars alignment in a Split Hopkinson Pressure Bar influences the quality of signal recorded during experiments, and thus affects the data of material properties being measured. There are some parameters directly related to the bars alignment such as their straightness, the impact face parallelism, and the neutral axis offset.
