A new acoustoelastic model for velocity-hydrostatic-pressure in rocks based on general acoustoelastic theory for elastic solids

open access: yesSN Applied Sciences, 2022
Acoustoelastic model based on classic acoustoelastic theory of solids fails to describe rock acoustoelasticity, where wave velocities in rocks has complex non-linear relations with the applied hydrostatic pressure. In order to extend acoustoelastic model

Entropy Principle and Shock-Wave Propagation in Continuum Physics

open access: yesMathematics, 2022
According to second law of thermodynamics, the local entropy production must be nonnegative for arbitrary thermodynamic processes. In 1996, Muschik and Ehrentraut observed that such a constraint can be fulfilled in two different ways: either by ...

A simple yet consistent constitutive law and mortar-based layer coupling schemes for thermomechanical macroscale simulations of metal additive manufacturing processes

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2021
This article proposes a coupled thermomechanical finite element model tailored to the macroscale simulation of metal additive manufacturing processes such as selective laser melting.

Converging shocks in elastic-plastic solids [PDF]

open access: yes, 2011
We present an approximate description of the behavior of an elastic-plastic material processed by a cylindrically or spherically symmetric converging shock, following Whitham's shock dynamics theory.

Thermodynamically consistent gradient elasticity with an internal variable

open access: yes, 2020
The role of thermodynamics in continuum mechanics and the derivation of the proper constitutive relations is a discussed subject of Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical ...

Compressive Deformation Analysis of Alginate-Poly(L)lysine-Alginate (APA) Microcapsule

open access: yesJournal of Biomechanical Science and Engineering, 2013
An analysis of the compressive deformation of alginate-poly(L)lysine-alginate (APA) microcapsules by two rigid parallel plates was performed under the assumptions that the bending stiffness and permeability of the membrane were negligible.

Creep constitutive law prediction via short-term evaluation using a small size testing method

open access: yesEnergy Reports, 2023
To efficiently assess the mechanical reliability and long-term durability of solid oxide fuel cells (SOFCs) and solid oxide electrolyser cells (SOECs), a suitable creep test method and prediction of the material response is necessary.

Regulative Strategies in Arbitration Law Uncitral Model Law on International Commercial Arbitration (UNCITRAL) compared with Arbitration Law of the People's Republic of China

open access: yesHermes, 2004
This paper is concerned with the laying down of the law in international and domestic arbitration. Interest centres on regulative and constitutive functions, and an analysis of realisation patterns of regulative (directive) acts is reported.

A Neural Network Constitutive Model and Automatic Stiffness Evaluation for Multiscale Finite Elements

open access: yesApplied Sciences
A neural network model for a constitutive law in nonlinear structures is proposed in this paper. The artificial neural network (ANN) model is constructed based on a data set of responses from representative volume elements, which was calculated by finite

LEGAL PROTECTION VERSUS LEGAL CONSCIOUSNESS (The changing Perspective in Law and Society Research)

open access: yesAl-Banjari: Jurnal Ilmiah Ilmu-Ilmu Keislaman, 2016
Considering the important role of historical, cultural, social, and attitudinal aspects in the study of law, there has been a shift from instrumental law to constitutive law.
