PhD Positions Available in Solid Mechanics and Advanced Materials

Submitted by Lifeng Wang on

Two PhD positions are available immediately in the Department of Mechanical Engineering at State University of New York (SUNY) Stony Brook University, New York, US.

The research program is about mechanics and multifunctional applications of new advanced materials (such as polymer cellular solids, polymer composites, and metamaterials) focusing on mechanical performance, 3D printing, acoustic/elastic wave propagation, energy absorption, and impact resistance. The candidates with background in solid mechanics and finite element analysis are highly encouraged to apply.

Nine papers about fatigue modelling of short fiber composite

Submitted by Atul Jain on

Recently, we have published a series of nine papers about modelling fatigue and damage in short fiber composites.  Together, they provide a complete description of modelling of such materials including wavy fiber composites; starting from appropriate homogenization method to component level fatigue simulation. Discussion and feedback on the papers is welcome.

Effects of Nanoporosity on the Mechanical Properties and Applications of Aerogels in Composite Structures

Submitted by Jingjie Yeo on

Newly published book chapter - http://link.springer.com/chapter/10.1007/978-3-319-31662-8_4 Aerogels are ultralight solids with nanoporous structure and are one of the world’s lightest materials available in the market. It is a dry gel, principally made up of 99.8 % of air and weighing just around three times that of air. The first aerogels were realized in 1931, when Kistler (J Phys Chem 36:52–64, 1932) attempted to remove liquid from a wet gel.

RVE analysis without BCs and periodic mesh requirements

Submitted by Wenbin Yu on

RVE analysis becomes a routine exercise in material modeling. Usually it is carried out using finite element codes such as ABAQUS or ANSYS. The main thing one should pay attention is to applying the right boundary conditions. It is settled that periodic boundary conditions are the preferred boundary conditions to be applied. The BCs are that u_i-\epsilon_{ij}x_j should be equal on the corresponding edges. This type of boundary conditions can be applied using coupled equations constraints. This requires that one creates a mesh with corresponding nodes on periodic edges.
