The Buckling of Single-Layer MoS2 Under Uniaxial Compression

, 2014
Molecular dynamics simulations are performed to investigate the buckling of single-layer MoS2 under uniaxial compression. The strain rate is found to play an important role on the critical buckling strain, where higher strain rate leads to larger ...

Simple evaluation method of adhesive failure criterion in multiaxial stress states by uniaxial tensile tests

Mechanical Engineering Journal, 2018
We propose a simple tensile test with which to identify the parameters that constitute the failure criterion of an adhesive in a multiaxial stress state. In this paper, we define the failure criterion as the proportional limit of load-displacement curves

Relaxation oscillations and negative strain rate sensitivity in the Portevin - Le Chatelier effect

, 2000
A characteristic feature of the Portevin - Le Chatelier effect or the jerky flow is the stick-slip nature of stress-strain curves which is believed to result from the negative strain rate dependence of the flow stress.

Shear band dynamics from a mesoscopic modeling of plasticity

, 2010
The ubiquitous appearance of regions of localized deformation (shear bands) in different kinds of disordered materials under shear is studied in the context of a mesoscopic model of plasticity.

A Degradation Function Consistent with Cocks–Ashby Porosity Kinetics [PDF]

, 2018
The load carrying capacity of ductile materials degrades as a function of porosity, stress state and strain-rate. The effect of these variables on porosity kinetics is captured by the Cocks–Ashby model; however, the Cocks–Ashby model does not account for

Constitutive Model Based on Stress Relaxation for Composite Modified Double-Base Propellants and Master Curve of Relaxation Modulus

Aerospace
This study investigates the constitutive model and relaxation modulus master curve of composite modified double-base (CMDB) propellants through uniaxial constant-rate tensile tests and stress relaxation tests.

Rate Dependence and Role of Disorder in Linearly Sheared Two-Dimensional Foams

, 2008
The shear flow of two dimensional foams is probed as a function of shear rate and disorder. Disordered foams exhibit strongly rate dependent velocity profiles, whereas ordered foams show rate independence.

Strain in epitaxial CoSi2 films on Si (111) and inference for pseudomorphic growth [PDF]

, 1989
The perpendicular x-ray strain of epitaxial CoSi2 films grown on Si(111) substrates at ~600 °C was measured at temperatures from 24 up to 650 °C. At 600 °C, the perpendicular x-ray strain is –0.86%, which is about the x-ray strain that a stress-free ...

Mechanical behavior of HTCE propellant: Dependence on strain rate and temperature

Polymer Testing
High-solid-content polymer composites such as solid propellants are widely used in different fields. Although the proportion of polymer components in the material is relatively low, the mechanical influence of polymers on composite materials is crucial ...
