In-situ measurements of stress evolution in composite sulfur cathodes

Owing to their enormous capacities, Li-S batteries have emerged as a prime candidate for economic and sustainable energy storage. Still, potential mechanics-based issues exist that must be addressed: lithiation of sulfur produces an enormous volume expansion (~80%). In other high capacity electrodes, large expansions generate considerable stresses that can lead to mechanical damage and capacity fading.

Stress update scheme in platicity

Hi everybody,

I am studying the plastic deformation of sheet metal. Recently, I study about stress update scheme in finite element analysis using return mapping method. For this problem, we can calculate the increment of stress components, Δσ for a given value of strain components Δε using elastic predictor - plastic correct scheme. Since Δε = Δεe +Δεp, first, we assume Δεp=0 and check the yield criterion. Then, we find Δεp to satisfy the yield criterion as well as the consistent condition.

However, I have a question as the follows

ABSTRACT

Optimal-Feedback Accelerated Picard Iteration Method and a Fish-Scale Growing Method for Wide-Ranging and Multi-Revolution Perturbed Lambert's Problems

Wide-ranging and multiple-revolution perturbed Lambert’s problems are building blocks for practical missions such as development of cislunar space, interplanetary navigation, orbital rendezvous, etc. However, it is of a great challenge to solve these problems both accurately and efficiently, considering the long transfer time and the complexity of high-fidelity modeling of space environment. For that, a methodology combining Optimal-Feedback Accelerated Picard Iteration methods and Fish-Scale Growing Method is demonstrated.

A review on modeling of electro-chemo-mechanics in lithium-ion batteries

Investigations on the fast capacity loss of Lithium-ion batteries (LIBs) have highlighted a rich field of mechanical phenomena occurring during charging/discharging cycles, to name only a few, large deformations coupled with nonlinear elasticity, plastification, fracture, anisotropy, structural instability, and phase separation phenomena. In the last decade, numerous experimental and theoretical studies have been conducted to investigate and model these phenomena.

PhD Positions @ the University of Wisconsin-Madison in Hybrid Composites

Two PhD positions are available starting Summer/Fall 2019 in the Manufacturing and Mechanics Lab (MaMeL) within the Civil and Environmental Engineering Department at the University of Wisconsin-Madison under the supervision of Professor Pavana Prabhakar. The research topic is in the area of Mechanics of Hybrid Composites, and will involve theoretical/computational multiscale and multiphysics modeling in combination with experimental manufacturing and characterization studies.
