Eigenstrains in nonlinear elastic solids are created through defects, growth, or other anelastic effects. These eigenstrains are known to be important as they can generate residual stresses and alter the overall response of the solid. Here, we study the residual stress fields generated by finite torsional or shear eigenstrains. This problem is addressed by considering a cylindrical bar made of an incompressible isotropic solid with an axisymmetric distribution of shear eigenstrains.

Postdoctoral position is open at the "Technologie des Polymères et Composites & Ingénierie Mécanique" (MINES-Douai, France). This project is a part of the European project JOIN'EM. Candidate is expected to conduct enriched FEM simulation and should have strong background in the mechanics of composites (multi-scale modelling and fatigue damage). The following experience is expected from the candidate, i.e. coding and/or scripting, fatigue damage simulation and material model development (ABAQUS/UMAT). 

Cracks typically follow paths that locally give a mode I crack tip load. At mixed modes crack are extended via a kink in a direction that locally restores mode I. In isotropic materials this is known to more or less, true for static and dynamic loads. Exceptions are cracks that are subjected to high compressive load, e.g., at contact between train wheels and rails or at cracks caused by seismic movements. Other exceptions are cracks growing in anisotropic materials, at grain boundaries or other weak, or by deformation weakened, interfaces.

The aim of this post is to introduce the mechanics of structure genome (MSG) as a possible unified approach for constitutive modeling of structures and materials. Because this discussion relates with structural mechanics and micromechanics, two familiar topics which have been studied by many, it is difficult to cite all the relevant references in a blog post without missing important ones. Thus, I only share some general understanding of relevant topics which are available from typical textbooks.

The Blast Impact and Survivability Research Unit (BISRU) in the Department of Mechanical Engineering at the University of Cape Town, is seeking candidates for a Postdoctoral Research Fellowship. The candidate would conduct research in the area of failure of fibre reinforced polymers and sandwich panels under extreme loading (blast and or impact), with a focus on erosion  / pulverisation of the FRP face sheets. Candidates must have completed a PhD or be able to show evidence of submission.

Dear Colleagues,

We invite you to submit an abstract for the 'Dynamic Behavior of Composites' under session track 1 'Dynamic Behavior of Materials' for the upcoming SEM XIII international Conference in Orlando, FL June 6-9, 2016

Three graduate student positions are available at Polytechnique Montréal in the field of fire resistance of composite materials. The use of materials based on lightweight composite and aluminum, although common in other parts of the aircraft, remains a challenge around the engines because of the fire resistance prescribed by certification requirements. The present project focuses on the use of such materials for the manufacturing of fan cases and bypass ducts for turbofan aircraft engines.
