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

Liu, M., Suo, S., Wu, J., Gan, Y., Hanaor, D. A. H., & Chen, C. Q. Journal of Colloid and Interface Science, 2019, 539: 379-387. https://www.sciencedirect.com/science/article/pii/S0021979718315108#f00…

Hypothesis

In this paper, we experimentally characterize a simple and unified power law for the profiles of a variety of nanobubbles and nanotents formed by 2D materials such as graphene and MoS2 layers. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.121.266101

ABSTRACT

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.

Vacancy exists for high calibre one postdoctoral fellow to join the Innovative Design and Engineering Analysis Laboratory at York University, starting immediately.
The position’s primary area of research will focus on characterization and modelling of elastomers subject to high strain rates.

Dear colleagues, 

On behalf of the co-organizers, I would like to draw to your attention to the mini-symposium #1401 on Computational Geomechanics in the upcoming 15th NS National Congress on Computational Mechanics, to be held at Austin Texas from July 28th to August 1st, 2019. The due date of abstract submission is January 15th, 2019. 

Further information can be found at http://15.usnccm.org/1401

The scope of the mini-symposium is listed below.

Thanks, 

Steve Sun

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.

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.
