An experimental method to measure dynamic stress-strain relationship of materials at high strain rates [PDF]

open access: yes, 2014
In this paper, an experimental method for measuring dynamic behavior of materials at high strain rates is developed. The strain and stress of a specimen are obtained using a high-precision photonic Doppler velocimetry system and a sensitive ...

Plasticity and Deformation Mechanisms of Ultrafine-Grained Ti in Necking Region Revealed by Digital Image Correlation Technique

open access: yesNanomaterials, 2021
The conventional engineering stress-strain curve could not accurately describe the true stress-strain and local deformability of the necking part of tensile specimens, as it calculates the strain by using the whole gauge length, assuming the tensile ...

Bone Stress-Strain State Evaluation Using CT Based FEM

open access: yesFrontiers in Mechanical Engineering, 2021
Nowadays, the use of a digital prototype in numerical modeling is one of the main approaches to calculating the elements of an inhomogeneous structure under the influence of external forces. The article considers a finite element analysis method based on

On stress/strain state in a rotating disk

open access: yesJournal of Physics: Conference Series, 2019
In the framework of mechanics of continuum bodies, the problem of stress/strain state in a high-speed rotating disk of constant thickness has been considered. The material of the disk is assumed to be homogeneous, elastic/perfectly-plastic. In the plastic zone, the stresses and plastic strains are related by some associated law similar to the one ...
