interface mechanics

While the surface asperities of mineral platelets are widely believed to play important roles in stiffening, strengthening, and toughening nacre, their effects have not been thoroughly investigated. Here, a computationally efficient bar-spring model is adopted to simulate, as platelets with multiple interfacial asperities slide over each other, the tensile force versus elongation behaviors as well as the effective mechanical properties such as modulus, strength, and work-to-fracture in nacre or nacre-like composites.

In this progress report, we reviewed recent advances in strategies for applying mechanical strain into 2D materials and recent state‐of‐the‐art characterizations of interface mechanics for 2D material–substrate systems.

PhD and Post-Doc positions are now available at the Institut für Angewandte Mechanik of the Technische Universität Braunschweig, Germany. Both are full-time fixed-term positions for 2 years with the possibility of renewal.

3 PhD positions are now available at the Department of Innovation Engineering at the University of Salento in Lecce, Italy. Funding is provided by the European Research Council Starting Researcher Grant project "INTERFACES-Mechanical Modeling of Interfaces in Advanced Materials and Structures".

The successful applicant will work on topics related to computational methods for interface modeling, isogeometric analysis, and multiscale methods.

Applicants should possess the following qualifications/attributes:

Postdoc research fellows are needed in computational material science.  Experience in molecular level simulation of polymer/metal interfaces or CNT/Si and CNT/Cu interfaces are required.  Please send detailed academic CV to Jianmin Qu at jq [at] gatech.edu (jq[at]gatech[dot]edu)
