micromechanics

An extended abstract dedicated to nonlocal (in the sense of either Eringen or Silling) micromechanics is attached. It can’t be considered as a review in any sense. It is just a personal vision on a new area of micromechanics, in particularly based on the author’s publications (references on hundreds related papers can be found in the referred publications). The style of the abstract is plausible rather than rigorous that willfully used by the author just for initiation of discussions in the new prospective area of micromechanics.

We have published a paper called "Micromechanical model for prediction of the fatigue limit for unidirectional fibre composites" in Mechanics of Materials. See the link here.

A new PhD position is vacant at the Section of Composites and Materials Mechanics of the Department of Wind Energy at the Technical University of Denmark (DTU). The PhD project will concern damage tolerance of composite materials subjected to static and cyclic loading. The objective is to creacte enhanced fracture resistance by facilitating the formation of multiple cracks with large-scale fiber bridging along the interfaces in a layered composite by controlled mechanical properties by surface treatments.

Project title: Micromechanical modeling of geomaterials by considering the microstructural anisotropy 

Location: Nancy (France), Georessources Laboratory, University of Lorraine

Starting date and duration: September/October, 2018, 3 years

Candidates: First-class undergraduate and master degrees in mechanics, applied mathematics, civil engineering or other related disciplines. The candidates should be motivated by research in theoretical and numerical modeling and have a good background in mathematics, mechanics of materials, finite element method, etc. 

Call for papers: Special issue of IJMCE journal on Multiscale multiphysics modellig of materials

Herein, we report a theoretical study of polymeric nanocomposites to provide physical insight into complex material systems in elastic regions. A self-consistent scheme is adopted to predict piezoresistive characteristics, and the effects of the interface and of tunneling on the effective piezoresistive and electrical properties of the nanocomposites are simulated. The overall piezoresistive sensitivity is predicted to be reduced when the lower interfacial resistivity of multi-walled carbon nanotubes (MWCNTs) and the higher effective stiffness of nanocomposites are considered.

We anticipate an opening for a post-doctoral fellow position in micromechanics based failure modeling of heterogeneous brittle materials. The focus will be on characterizing the roles of flaw distributions on rate-dependent failure in materials such as concrete. The objective is to develop an understanding of failure processes with the aim of designing high performance brittle materials.
