Journal Club Theme of October 2015: Mechanics of Structure Genome

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.

ASME AMD Award Nominations 2015

Traditionally, the deadline for ASME AMD awards nominations has been the 5th of November. However, starting from this year, the AMD executive committee instituted the new deadline of October 1st (see the earlier announcement here). This was done to allow the various awards committee members adequate time to review the growing number of nomination well before the IMECE annual conference.

The Twist-Fit Problem: Finite Torsional and Shear Eigenstrains in Nonlinear Elastic Solids

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.

PostDoc position

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).

Discussion of fracture paper #12 - Crack paths and fracture process region autonomy

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.

PhD positions in Mechanical Engineering at Polytechnique Montréal

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.

The Weak Compatibility Equations of Nonlinear Elasticity and the Insufficiency of the Hadamard Jump Condition for Non-Simply Connected Bodies

We derive the compatibility equations of L2 displacement gradients on non-simply-connected bodies. These compatibility equations are useful for non-smooth strains such as those associated with deformations of multi-phase materials. As an application of these compatibility equations, we study some configurations of different phases around a hole and show that, in general, the classical Hadamard jump condition is not a sufficient compatibility condition.
