Hi,



I'm an Engineer and a Ph.D. student in Applied Maths, working in the field of Nonlinear Finite Elements for Elasticity. I often think about my future career since, by now, I have a strong experience with coding FE in C++/Matlab/Mathematica, but no clue whatsoever about commercial black-box softwares for FEA. I'm worried about this, since most of the job vacancies from the industry (I'm not interested in pursuing the Academic career) seem to require only experience with a specific software and application, and not to directly code FE.

A year ago in my first post, The Future of Ink, I explored e-ink technology and the e-book concept when the potential was still largely unseen. But since then, the industry has completely transformed, and the prospect of the e-book is beginning to be realized.

Abstract 

In one design of flexible electronics, thin-film islands of a stiff material are fabricated on a polymeric substrate, and functional materials are grown on these islands. When the substrate is stretched, the deformation is mainly accommodated by the substrate, and the islands and functional materials experience relatively small strains. Experiments have shown that, however, for a given amount of stretch, the islands exceeding a certain size may delaminate from the substrate. We calculate the energy release rate using a combination of finite element method and complex variable method. Our results show that the energy release rate diminishes as the island size or substrate stiffness decreases. Consequently, the critical island size is large when the substrate is compliant. We also obtain an analytical expression for the energy release rate of debonding islands from a very compliant substrate.

The mobility of charge carriers in silicon can be significantly increased when silicon is subject to a field of strain.In a microelectronic device, however, the strain field may be intensified at a sharp feature, such as an edge or a corner, injecting dislocations into silicon and ultimately failing the device. The strain field at an edge is singular, and is often a linear superposition of two modes of different exponents. We characterize the relative contribution of the two modes by a mode angle, and determine the critical slip systems as the amplitude of the load increases. We calculate the critical residual stress in a thin-film stripe bonded on a silicon substrate.
