Hot tensile deformation behavior and a fracture damage model of the wrought Mg–Gd−Y–Zn–Zr alloy

Journal of Materials Research and Technology, 2023
The hot deformation behavior of the wrought Mg–Gd−Y–Zn–Zr alloy was studied by uniaxial tensile tests conducted at various temperatures (350–500 °C) and strain rates (0.1–0.0001s−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.

Sheared edge formability of multi-phase steels under in- and out-of-plane deformation [PDF]

MATEC Web of Conferences
Multi-phase advanced high strength steels can exhibit significant sheared edge sensitivity due to their microstructures and alloying elements. Processing defects such as centerline segregation of martensite or Ti-based inclusions can affect edge ...

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).
