The Louisiana State University School of Civil and Environmental Engineering seeks a postdoctoral researcher to work with the Computational Solid Mechanics (CSM) Research Group on research projects pertaining to computational material modeling and simulation due to a variety of causes including high impact damage, explosions due to energetic materials, other extreme loading conditions, etc. The researcher will also work in strain gradient plasticity to address the characteristics of microstructural material behavior such as size effects and numerical instabilities of shear bands.

We have an immediate opening for a Postdoc Associate and a new PhD Position for the Fall 2020 in the Laboratory for Soft Machines & Electronics (www.caogroup.org) at the Michigan State University. The research work is highly multi-disciplinary, and specific topics includes: Energy harvesters; Sensors and actuators; Artificial skins; soft (active) materials and machines; printed electronics and batteries.

Qualifications for Postdoc Position:

Thanks. 

We are looking for two motivated PhD students to join us in Spring 2020. The successful candidate should have a strong background in continuum mechanics and be proficients in programming. Please take a look at the attached descriptions. 

In this paper, a continuum–atomistic multi-scale method is presented in modeling the nonlinear behavior of nano-materials under large deformation. In order to identify an appropriate strain energy function for crystalline nano-structures with different percentages of spherical voids, the hyperelastic method is employed for specimen whose behavior is determined based on the molecular dynamics analyses. In the atomistic level, the EAM many-body potential is employed to model the interactions between the atoms of Al RVEs.

We invite applications for a postdoctoral position and fully funded Ph.D. positions at the Department of Naval Architecture and Marine Engineering of the University of Michigan, Ann Arbor, in the general area of advanced manufacturing with an emphasis on dissimilar materials joining innovation and high-speed solid-state additive manufacturing. The research will serve as key enabler for high-volume production of next-generation multi-material lightweight structures in automobiles, trains, ships, and aircraft.

Our group has recently published an article in which, for the very first time, we measure the compressive strength of hydrated cement paste at multi-metre length scale. This study shows that microscopic strength of cement-based materials is many times higher compared to their macroscopic strength.

The Materials Mechanics Center (Technion) mourns the passing away of our respected colleague and founder of the Materials Mechanics Center, Prof. SOL BODNER. May he rest in peace. Our sincere condolences to his family.

The Soft Intelligent Materials Laboratory (https://zhaor.engineering.osu.edu/) directed by Prof. Renee Zhao is recruiting highly-motivated applicants to fill two open PhD positions (one in spring 2020 and one in autumn 2020) at the Ohio State University - Columbus.

Electrical Contact Resistance of Fractal Rough Surfaces 

The presence of roughness at electrical contacts tends to involve contacting asperities across multiple scales. Depending on the nature of the contact between asperities on opposing surfaces, different conduction mechanisms take place. This is shown in the figure here.
