Framework of Weapon Effects Calculator for Hardened Targets [PDF]

Journal of the Korea Institute of Military Science and Technology, 2013
Weapon effect is a key issue throughout the life cycle of weapon systems. Only when weapon effect is considered properly, Effects Based Operation(EBO), Effects Based Acquisition(EBA), and Effects Based Development(EBD) could be possible. Because the transfer of weapon effect technologies is restricted in most foreign counties, independent development ...

A finite strain thermo-mechanically coupled material model for semi-crystalline polymers [PDF]

, 2019
In this work, a thermo-mechanically coupled constitutive model for semicrystalline polymers is derived in a thermodynamically consistent manner. In general, the macroscopic material behaviour of this class of materials is dictated by the underlying ...

Ratcheting of Steel Samples Undergoing Asymmetric Loading Cycles at Elevated Operating Temperatures: Analytical and Numerical Assessments

Applied Sciences
The present study intends to assess the ratcheting response of SA508 and SA333 steel alloys subjected to asymmetric loading cycles at various operating temperatures of 298, 573, and 623K through a hardening framework developed by Ahmadzadeh–Varvani (A-V)

Dislocation-based constitutive model of crystal plasticity for the size effect of single crystalline micropillar samples

Mechanical Engineering Journal, 2016
In this study, based on the Orowan equation and the principle of Bergstrom dislocation evolution, the plastic mechanical response of single crystalline micropillars is investigated by considering dislocation evolution.

A systematic review of faculty development programs based on the Harden teacher’s role framework model

BMC Medical Education, 2023
Abstract Background Despite the changing roles of faculty in the health professions over the past two decades, none of the reviews has been paid enough attention to the impact of the faculty development programs on these roles.

Single cell mechanics: stress stiffening and kinematic hardening

, 2007
Cell mechanical properties are fundamental to the organism but remain poorly understood. We report a comprehensive phenomenological framework for the nonlinear rheology of single fibroblast cells: a superposition of elastic stiffening and viscoplastic ...

Implicit yield function formulation for granular and rock-like materials [PDF]

, 2014
The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or branches where the values go to infinity, or false elastic domains ...
