Rheological constitutive model for thermoplastic resin based on viscoplastic-viscoelastic multiplicative decomposition of deformation gradient

Nihon Kikai Gakkai ronbunshu, 2016
We propose a rheology-based viscoelastic-viscoplastic constitutive model in which the deformation gradient is mutiplicatively decomposed into viscoelastic and viscoplastic components.

Towards Viscoplastic Constitutive Models for Cosserat Rods

Archive of Mechanical Engineering, 2016
Flexible, slender structures like cables, hoses or wires can be described by the geometrically exact Cosserat rod theory. Due to their complex multilayer structure, consisting of various materials, viscoplastic behavior has to be expected for cables ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

The Viscoplastic Effect in the Heat–Treated, Thin–Walled AL–6060 Alloy Profiles Subjected to Compressive Axial Impact. [PDF]

, 2014
This paper will highlight the influence of the strain rate effect occurring during pulse loading on dynamic stability of aluminium profiles. Current work is the development of the analysis carried in [1].

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Two‐Phase Nanofluid Flow in a Non‐Newtonian Model Past a Deformable Sheet With Magnetized Environmental Effects: Statistical Modeling and ANOVA Analysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This paper presents a comprehensive numerical analysis of magnetohydrodynamic (MHD) Casson nanofluid movement over a permeable, linearly stretching sheet, integrating the contributions of non‐uniform heat generation or absorption and chemical interaction.

A Viscoplasticity Model for Shale Creep Behavior and Its Application on Fracture Closure and Conductivity

Energies
Hydraulic fracturing is the main means for developing low-permeability shale reservoirs. Whether to produce artificial fractures with sufficient conductivity is an important criterion for hydraulic fracturing evaluation.

Modeling and simulation of size effects in metallic glasses with a nonlocal continuum mechanics theory

Journal of the Mechanical Behavior of Materials, 2013
The present contribution is concerned with the modeling and computation of size effects in metallic glasses. For the underlying model description, we resort to a thermodynamically consistent, gradient-extended continuum mechanics approach.

Lie groups in nonequilibrium thermodynamics: Geometric structure behind viscoplasticity

, 2010
Poisson brackets provide the mathematical structure required to identify the reversible contribution to dynamic phenomena in nonequilibrium thermodynamics. This mathematical structure is deeply linked to Lie groups and their Lie algebras.
