Introduction
Dear Colleagues,
We would like to invite you to submit an abstract for a mini-symposium at International Conference on Nonlinear Solid Mechanics (ICoNSoM 2019) on “MS-18 Computational Fracture Mechanics” :
http://www.memocsevents.eu/iconsom2019/
We have openings for two positions of post-doc fellow in our research group in the College of Civil Engineering at the Hunan University, China. These positions will focus on the high performance composites in civil engineering, and bio-inspired composites for flexible armor. For the post-doc positions, in addition to a strong understanding of solid mechanics and materials, experience in FE modelling using LS-DYNA is highly desirable. For the faculty positions, the candidate should have strong research background in high performance construction materials (i.e.

We have openings for a PhD candidate and a post-doc fellow in our research group in the Department of Mechanical Engineering at the University of Houston. These positions will focus on the theoretical and computational modeling of damage in advanced materials.
For the PhD position, a strong background in solid mechanics is required; a good background in computational mechanics is highly desirable.

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
