Prediction of friction is one of the nigthmares of tribologists!   For elastomers, friction may be due to shear stresses or to dissipation and adhesion hysteresis.  Here we consider the two effects in rolling/ sliding a viscoelastic cylinder. We find that at low speeds the numerical bem results confirm Persson/Brener theory for crack propagation at large Tabor parameter.

Overview

 The Multiscale Mechanics and Multiphysics of Materials Lab (http://m4lab.unibs.it) at the School of Engineering at the University of Brescia, Italy announces a PhD fellowship on the subject of Modeling and simulations for next generation lithium-ion cells. The fellowship is fully funded and will last three years.

Multiple PhD positions are available for Fall 2024 in the Department of Physics or the Department of Mechanical Engineering at the University of Vermont in Dr. Jihong Ma's group. Successful candidates will work under the supervision of Prof. Jihong Ma on projects related to atomistic simulations of polymers. The candidates should have a strong background in physics, chemistry, and mathematics, and preferably have experience in MD and/or MM simulations. 

The Ocean Engineering Structures and Extreme Material Laboratory (OESEM) of the Department of Ocean Engineering at the Texas A&M University, Galveston has an opening for 1-year Postdoc position (which may be extended anually upon contract renewal) to conduct research in the areas of computational fracture modeling and fluid-structure interaction (FSI) of gaseous mixtures starting in July 2024.

Abstract: The present study aims to develop a continuum-based model to predict the pseudoelastic behavior of biological composites subjected to finite plane elastostatics. The proposed model incorporates a hyperelastic matrix material reinforced with nonlinear fibers, addressing challenges such as irreversible softening responses, large deformations, and nonlinear stress–strain responses.
