Visco-Elastoplastic Constitutive Fatigue Model for Rocks
Advances in Civil Engineering, 2020 The study on the constitutive fatigue model for rocks under cyclic loading has an important significance in rock engineering. In order to study the fatigue properties of rocks under cyclic loading, according to the theory of rheological mechanics and the

A constitutive model for Ti6Al4V considering the state of stress and strain rate effects
Mechanics of materials (Print), 2019 The predictability of manufacturing process simulation is highly dependent on the accuracy of the constitutive model to describe the mechanical behavior of the work material. The model should consider the most relevant parameters affecting this behavior.

A Simple Hysteretic Constitutive Model for Unsaturated Flow [PDF]
Transport in Porous Media, 2017 In this paper, we present a constitutive model to describe unsaturated flow that considers the hysteresis phenomena. This constitutive model provides simple mathematical expressions for both saturation and hydraulic conductivity curves, and a ...

A Solution Set-Based Entropy Principle for Constitutive Modeling in Mechanics
, 2018 Entropy principles based on thermodynamic consistency requirements are widely used for constitutive modeling in continuum mechanics, providing physical constraints on a priori unknown constitutive functions. The well-known M\"uller-Liu procedure is based

Efficient and robust constitutive integrators for single-crystal plasticity modeling [PDF]
, 2005 Simulations of the dynamic deformations of metal samples require elastic-plastic constitutive updates of the material behavior to be performed over a small time step between updates, as dictated by the Courant condition.

Rate- and State-Dependent Friction Law and Statistical Properties of Earthquakes
, 2006 In order to clarify how the statistical properties of earthquakes depend on the constitutive law characterizing the stick-slip dynamics, we make an extensive numerical simulation of the one-dimensional spring-block model with the rate- and state ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
