Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

open access: yesAdvanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...
