Bipotentials for non monotone multivalued operators: fundamental results and applications [PDF]

open access: yes, 2008
This is a survey of recent results about bipotentials representing multivalued operators. The notion of bipotential is based on an extension of Fenchel's inequality, with several interesting applications related to non associated constitutive laws in non

Enhancement of a Constitutive Friction Law by Considering Plastic Smoothing of Rough Surfaces in Dependency on the Bulk Stresses [PDF]

open access: yesTribology in Industry, 2016
The aim of this work is the improvement of a constitutive friction law which has been identified for the specific demands of sheet-bulk metal-forming.

A Dynamic Cavity Expansion Model for Rigid Projectile Penetration into Concrete considering the Compressibility and Nonlinear Constitutive Relations

open access: yesGeofluids, 2021
The P-α equation of state (EOS) and a nonlinear yield criterion are utilized to characterize the dynamic constitutive behavior of concrete targets subjected to projectile normal penetration.

A Three-Field Variational Formulation for a Frictional Contact Problem with Prescribed Normal Stress

open access: yesFractal and Fractional, 2022
In the present work, we address a nonlinear boundary value problem that models frictional contact with prescribed normal stress between a deformable body and a foundation.

Earthquake response of adjacent structures with viscoelastic and friction dampers [PDF]

open access: yesTheoretical and Applied Mechanics, 2015
We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base.

Thermo-hydro-mechanical behavior of a clayey rock: A constitutive approach and numerical validation

open access: yesCase Studies in Thermal Engineering, 2022
Temperature strongly affects the thermo-hydro-mechanical properties of clayey rocks. Using the Drucker–Prager Cap model and available experimental results, an advanced constitutive model is proposed to describe the influence of temperature on the hydro ...

Rate- and State-Dependent Friction Law and Statistical Properties of Earthquakes

open access: yes, 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 ...

Crucial role of side walls for granular surface flows: consequences for the rheology

open access: yes, 2005
In this paper we study the steady uniform flows that develop when granular material is released from a hopper on top of a static pile in a channel. We more specifically focus on the role of side walls by carrying out experiments in setup of different ...
