UT-Austin Engineering Mechanics Program is well known for its research on experimental mechanics, computational mechanics, fracture mechanics, nano- and micro-mechanics, thin-film mechanics, biomechanics, soft material mechanics, structural dynamics, and so on. We are the home of the International Journal of Solids and Structures (IJSS), International Journal of Fracture, and Computer Methods in Applied Mechanics and Engineering. We offer more than 20 rigorous graduate courses on engineering mechanics.

The Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin is ranked #8 best graduate program by US News. We currently have a tenure-track position in the area of Experimental Nano/Micro-Mechanics beginning Fall 2022.

Dear colleagues,

You are cordially invited to submit abstract(s) to Symposium D-12 Mechanics, Materials, and Manufacture of Flexible and Stretchable Electronics at the 2016 SES meeting to be held at the University of Maryland-College Park during October 2-5, 2016. Abstracts can not be more than 350 words and are due on Wednesday, June 15, 2016.

Introduction

Dear colleagues and friends, 

On behalf of the editorial board, I would like to introduce our new Journal, Soft Robotics (SoRo) to the mechanics community. SoRo is an innovative peer-reviewed journal dedicated to the science and engineering of soft materials in mobile machines. The Journal breaks new ground as the first to answer the urgent need for research on robotic technology that can safely interact with living systems and function in complex natural or human-built environments.

Dear Colleagues,

On behalf of the organizing committee, I cordially invite your participation in Symposium on Wrinkled and Crumpled Membranes, as part of the 13th Pan-American Congress of Applied Mechanics (PACAM XIII), to be held in Houston, Texas, May 22-24, 2013.

Dear colleagues,

We would like to invite you to submit an abstract to a Symposium on Mechanics of Integrated Structures and Materials in Advanced Technologies at the ASME 2012 IMECE, to be held Nov 9-15, 2012, at Houston Texas. This symposium will be the seventh in such a symposium series organized by ASME Technical Committee of Integrated Structures since IMECE 2006. We hope you can join us and continue the success of this symposium series.

Deadline of abstract submission is Monday, 27 Feb. 2012.

We perform uniaxial tensile tests on polyimide-supported copper films with a strong (111) fiber texture and with thicknesses varying from 50 nm to 1 μm. Films with thicknesses below 200 nm fail by intergranular fracture at elongations of only a few percent. Thicker films rupture by ductile transgranular fracture and local debonding from the substrate. The failure strain for transgranular fracture exhibits a maximum for film thicknesses around 500 nm.

An electronic device integrates diverse materials, and inevitably contains sharp features, such as interfaces and corners. When the device is subject to thermal and mechanical loads, the corners develop intense stress and are vulnerable sites to initiate failure. This paper analyzes stress fields at corners in flip-chip packages. The stress at a corner is a linear superposition of two modes of singular fields, with one mode being more singular than the other. The amplitudes of the two modes are represented by two stress intensity factors of dissimilar dimensions.

SERC launched the A*STAR Investigatorships last year. This prestigious award for top young research talent, tenable at their research institutes, aims to nurture young talent and build R&D capabilities in Singapore.

This year, the award is open for applications in the following areas:

The Singapore International Graduate Award (SINGA) is a collaboration between the Agency for Science, Technology & REsearch (A*STAR), the National Unviersity of Singaproe (NUS) and the Nanyang Technological University (NTU). PhD training will be carried out in English at your chosen lab at A*STAR Research Institutes, NUS or NTU. Students will be supervised by distinguished and world-renowned researchers in these labs. Upon successful completion, students will be conferred a PhD degree by either NUS or NTU.
