Ph.D. position in Mechanics of Advanced Multifunctional Materials - Technion – Israel Institute of Technology

Ph.D./Master position in the field of mechanics of materials is available at the Department of Aerospace Engineering, Technion - Israel Institute of Technology. The position starts on Oct. 1, 2014 or soon thereafter. Excellent candidates with deep knowledge in nonlinear elasticity, experience in finite element simulations, and/or with strong experimental background are encouraged to apply. Our group employs a mix of theoty, numerical simulations and experiments combined with 3D printing.

Wrinkling of Interfacial Layers in Stratified Composites

by Y. Li, N. Kaynia, S. Rudykh and M. C. Boyce  Massachusetts Institute of Technology [img_assist|nid=14796|title=Wrinkling of Interfacial Layers in Stratified Composites|desc=          Wrinkling vs. long-wavelength instability envelope for multi-layered soft composite: Predictive analytical and finite element models are presented to reveal the instability mechanics governing reversible wrinkling of interfacial layers.

Analysis of microstructural induced enhancement of electromechanical coupling in soft dielectrics

Electroactive soft elastomers require huge electric field for a meaningful actuation. We demonstrate, by means of numerical simulation, that this can be dramatically reduced and large deformations can be achieved with suitably designed heterogeneous actuators. The mechanism by which the enhancement is attained is illustrated with the aid of both idealized and periodic models.
