Call for papers: Soft Robotics - a new journal dedicated to soft machines

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.

Call for abstract-ASME IMECE 2012 Track 9-35 Symposium on Integrated Structures and Materials in Advanced Technologies

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.

The effect of film thickness on the failure strain of polymersupported metal films

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.

Singular stress fields at corners in flip-chip packages

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.

Singapore International Graduate Award (SINGA)

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.
