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.

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.

Does anyone know how to use umat written in C code with ABAQUS installed in Linux?

Since there are some weird problems occurred during the compiling with the application of VS and ABAQUS in Windows system, my supervisor advised me to use Linux system instead. The reason is that the system of the server of the institute is Linux and Linux helps a lot regarding coding. However, when I tried to run umat.o file in ABAQUS with the server, there was an error called "Problem during linking". I'm sure the server has installed ABAQUS and Intel Fortran.

A light-powered ultralight tensegrity robot with high deformability and load capacity

In our recent work, we construct a hybrid light-powered tensegrity robot composed of both hard and soft materials. The tensegrity robot shows great scalability, deployability, impact-mitigation capability, high load capacity, and can be precisely controlled to move on multiterrains. It is an example of combining interesting structures and interesting actuating materials in soft robotics.
