The LESION (CENTRAL NERVOUS SYSTEM BIOMECHANICS) Laboratory at the University of Mississippi's Department of Biomedical Engineering is seeking graduate students (PhD, MSc).

The LESION Lab aims to develop imaging and modeling tools for the understanding, diagnosis, and treatment of central nervous system disorders, with a particular focus on diseases related to the eye and brain, such as glaucoma and traumatic brain injury.

A point that has been overlooked is whether plastic anisotropy affects the thermomechanical coupling, expressed via the Taylor Quinney coefficient.
In a paper to appear in IJ. Eng. Sc., Gleb Gil Goviazin and I address this issue experimentally. The abstract follows:
An nteresting point that G. Goviazin and I report about in a paper to appear in Int. J. Eng. Science.

Are you interested in developing Digital Twin technology for machines and structures? Do you have experience with virtual/hybrid testing and/or structural health monitoring? Are you eager to bridge the gap between structural engineering and cyber-physical system engineering? Then the Department of Civil and Architectural Engineering invites you to apply for a 1.0-year Postdoc position funded by the IFD project “Cyber-physical systems for machines and structures – CP-SENS.”

Abstract

Exploiting the framework of peridynamics, a dimensionally-reduced formulation for plates is developed that allows for the through-thickness nucleation and growth of fracture surfaces,

 Dear colleagues,

Allow me to bring to your attention the 3rd edition of the International Workshop on Plasticity, Damage and Fracture of Engineering Materials, to be held in Istambul on October 4-6, 2023 (Link) 

Dear Colleagues,

I invite you to read our recent publication on Acta Materialia on the dynamic hardness evolution in metals.

I. Introduction

In this paper we formulate and solve the initial-boundary value problem of accreting circular cylindrical bars under finite extension. We assume that the bar grows by printing stress-free cylindrical layers on its boundary cylinder while it is undergoing a time-dependent finite extension. Accretion induces eigenstrains, and consequently residual stresses. We formulate the anelasticity problem by first constructing the natural Riemannian metric of the growing bar. This metric explicitly depends on the history of deformation during the accretion process.
