PhD Position at McGill University in Architected Multifunctional Materials

Submitted by Hamid.Akbarzadeh on

One PhD position is available for Fall 2019 in the Advanced Multifunctional and Multiphysics Metamaterials Lab (AM3L) in the Bioresource Engineering Department of McGill University. The research topic is on the area of Mechanics of Architected Multifunctional Materials. Theoretical and computational multiscale modelling along with experimental (3D printing and characterization) studies will be conducted for multiphysics analysis of architected cellular solids. The candidate will work under the supervision of Dr. Hamid Akbarzadeh at McGill University.

 

On the wrinkling and restabilization of highly stretched sheets

Submitted by Fan Xu on

Wrinkles are commonly observed in uniaxially stretched rectangular sheets with clamped-clamped boundaries, and can disappear upon excess stretching. Here we explore this wrinkling and restabilization behavior both analytically and numerically. We find that Poisson’s ratio plays a crucial role in the wrinkling and restabilization behavior. Smaller Poisson’s ratio makes later onset of wrinkling, lower amplitude and earlier disappearance of wrinkles.

Review: fatigue of hydrogels

Submitted by Ruobing Bai on

Here is our review article on fatigue of hydrogels. This is the first review of the subject. We review fatigue as any failure of material under prolonged static or cyclic loads. The paper starts with fundamentals, and covers a broad field, yet leaving a lot of interesting questions to be answered. The paper links the chemistry and mechanics of hydrogels.

The publisher now provides 50 days’ free access to the paper.

Multiple Doctoral Positions in Multiscale Modeling of Friction and Adhesion

Submitted by pastewka on

Adhesion and friction involving fluids or viscous matter, such as encountered in adhesives or in lubrication, are processes that determine everyday life, from human interaction with the environment to the function and reliability of machinery.

Phd / PostDoc position Additive Manufacturing - Polymers

Submitted by Andrei Constan… on

A postdoc or a PhD position are available immediately at the Laboratoire de Mecanique des Solides (Solid Mechanics) at https://www.polytechnique.edu/. The project is focused on understanding the impact of UV polymerization on the constitutive behaviour of printed polymer composites. The position is part of an ongoing collaboration with a german academic partner. The offers are detailed both in english and french on the job site of the CNRS (www.cnrs.fr): 

Multifunctional “Hydrogel Skins” on Diverse Polymers with Arbitrary Shapes

Submitted by hyunwoo on

In this paper, we introduce a new simple yet effective strategy to form "hydrogel skins" on polymer-based medical devices with arbitrary shapes. Hydrogel skins can convert any surface of polymer devices into robust, wet, soft, slippery, antifouling, and ionically conductive without affecting the original properties and geometries.

Abstract

Two Faculty Searches in Mechanical Engineering at Columbia

Submitted by Jeffrey Kysar on

The Department of Mechanical Engineering at Columbia University has two on-going faculty searches. 

In one search, we seek candidates to teach interdisciplinary classes related to mechanical engineering design, product design, and the design processes itself, with applications across all mechanical engineering disciplines including robotics, mechatronics, mechanical systems, thermal systems and energy systems.

In the second search, we seek candidates for an Open Topic and Open Rank search.

Doctoral Position in the area of Solid Mechanics for Triboelectricity and Metamaterials

Submitted by pastewka on

In this project, you will develop and apply numerical methods to gain insights into the mechanics of triboelectric nanogenerators and metamaterials. For both systems, the mechanical response is essential for the system’s function. In triboelectric generators, rough or patterned surfaces make contact and the mechanics of the interface determines contact area and stiffness and hence the charging efficiency. For metamaterials, the structural design of the individual unit cell determines the constitutive macroscopic response that can be designed in silico.
