Abstract
A demonstration through an example is given of how the Volterra dislocation formulation in linear elasticity can be viewed as a (formal) limit of a problem in plasticity theory. Interestingly, from this point of view the Volterra dislocation formulation with discontinuous displacement, and non-square-integrable energy appears as a large-length scale limit of a smoother microscopic problem. This is in contrast to other formulations using SBV functions as well as the theory of Structured deformations where the microscopic problem is viewed as discontinuous and the smoother plasticity formulation appears as a homogenized large length-scale limit.
The Department of Civil and Environmental Engineering (CEE) invites applications for several tenure-track faculty positions to begin July 2019 or thereafter. Appointments will be at the assistant or untenured associate professor level. In special cases, a senior faculty appointment may be possible.
The demand for higher specific capacity and rate capability has led to the adoption of nanostructured electrodes for lithium-ion batteries. At these length scales, surface effects gain an appreciable impact not only on the electrochemical and mechanical behavior of the electrode material, but also on defect thermodynamics. The focus of this study is the distribution of surface-induced bulk stresses in a LiCoO2 nanoparticle and their impact on the migration of Li vacancies. LiCoO2 is a prototypical cathode material, where the diffusion of Li is mediated by the vacancy mechanism.
The College of Engineering and Science at Louisiana Tech University is seeking self-motivated candidates for a Graduate Research Assistant (Ph.D. student) position, with the earliest starting date in Winter 2018.
Successful candidates will join the research group of Dr. Xiang (Shawn) Chen, who is in the research area of atomistic and multiscale simulation/modeling. A list of related publications can be found below: https://scholar.google.com/citations?user=qdz0cy4AAAAJ&hl=en
