Deformation and fracture behavior in TRIP steels under static and dynamic tensile conditions

Journal of Materials Research and Technology, 2022
The present study sought to explore the deformation and fracture behavior of Quenching and Partitioning (Q&P) steel at five different strain rates (10−4 s−1, 1 s−1, 10 s−1, 100 s−1 and 1400 s−1).

Biomechanical evaluation of different strain judging criteria on the prediction precision of cortical bone fracture simulation under compression

Frontiers in Bioengineering and Biotechnology, 2023
Introduction: The principal strain or equivalent strain is mainly used in current numerical studies to determine the mechanical state of the element in the cortical bone finite element model and then perform fracture simulation.

Nonadiabatic Study of Dynamic Electronic Effects during Brittle Fracture of Silicon [PDF]

, 2012
It has long been observed that brittle fracture of materials can lead to emission of high energy electrons and UV photons, but an atomistic description of the origin of such processes has lacked.
