The LEM3 laboratory (UMR 7239) of Arts et Métiers ParisTech, Metz announces 1 postdoc position.
Title: Modeling the fatigue behavior of thermomechanical shape memory alloys: Application to the optimization of biocompatible actuators for cardiac implants.
Applications are invited for two postdoctoral positions available immediately in the Aerospace Engineering Sciences Department at the University of Colorado Boulder. Advisors: Prof. Kurt Maute and Prof. Alireza Doostan.
We demonstrate intersting extension-torsion-inflation coupling in intrinsically twisted chiral tubes. In particular, we show that by tuning its intrinsic twist and the material constants, such tubes can show negative poison effect on being stretched. Similarly, such tubes can overwind initially when stretched - the same unusual behavior has been reported earlier when a DNA molecule is stretched.
We are looking for capable and responsible candidates for the following positions:
#1. We seek candidates with extensive experience in computational mechanics skills:
PhD in computational mechanics / applied math / applied physics
Statistics, Probability theory, Geometry, Graph theory, Reconstruction algorithms (for generating instantiations of virtual specimens) would be a big plus
Expertise in Linear and Non Linear Finite Element Analysis
We are looking for several capable and responsible candidates with good computational mechanics/solid mechanics skills to work on modeling metals and/or composite materials.
You will be involved in:
Constitutive modeling of metals and alloys and/or micromechanics modeling of plasticity mechanisms in metals and alloys;
Modeling damage progression in CFRP composite materials and/or meso-scale modeling of woven fabrics composites from X-ray CT-Scan imaging of actual specimens;
A postdoctoral researcher position is open in my group to work on multi-scale and inverse models for soft tissues and heart valve mechanics. The aim of this research will be to develop models that predict aortic stenosis - the most common valve-related disease that affects 5% of the elderly. The project is funded through the research council of UK, and will provide opportunities of working closely with clinicians and experimental collaborators.
Candidate is required to have:
There are ten days left to submit your abstract for the E-MRS Spring Meeting which will take place in Strasbourg, France, from May 22 to 26, 2017.

Cross-linked liquid crystalline polymers (LCPs) are smart materials for large light-activated variation or bend to transfer luminous energy into mechanical energy. We study the light-induced behavior of homeotropic nematic network polymer plates. The perturbation method is applied to find approximate solutions under uniform illumination and compared with finite element simulations. Moreover, situations of nonuniform laser illumination are investigated.
Inspired by the need to develop reconfigurable materials at the micro- and nano- scales that are capable of exhibiting more than one stable configuration, we employed both theoretical and computational models supported by experiments to study the multistable behavior of a Si/Cr microclaw and uncover the mechanical principles involved.
