A Novel Method to Describe Large-Range Stress-Strain Relations of Elastic-Plastic Materials Based on Energy Equivalence Principle

Materials, 2023
Due to the unique structure of tensile sheet specimens with a circular hole (CHS specimen), a novel method is proposed to predict the large-range uniaxial stress-strain relations of elastic-plastic materials analytically.

Asymmetry of tensile versus compressive elasticity and permeability contributes to the regulation of exchanges in collagen gels [PDF]

Science Advances, 2022
The Starling principle describes exchanges between blood and tissues based on the balance of hydrostatic and osmotic flows. However, the permeation properties of the main constituent of tissues, namely, collagen, in response to the stress exerted by ...

Bending-damaged fracture criterion and numerical implementation of limestone beam under three-point bending test

Frontiers in Earth Science, 2023
To study the characteristics of tensile cracking by rock-bending damage, the bending stress–strain curves and the cumulative ringing counts were obtained by a three-point bending test and acoustic emission (AE) monitoring of limestone beams. Based on the

Evidence for realignment of the charge density wave state in ErTe$_3$ and TmTe$_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

, 2022
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te$_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress.
