This paper explores the critical and post-bulging bifurcation of a cylindrical dielectric elastomer (DE) tube undergoing finite deformation under electro-mechanical coupling loading. Explicit expressions for the critical conditions of electro-mechanical bifurcation are derived by using a simplified mathematical method. The post-bifurcation path is comprehensively investigated by specifying the material model as ideal dielectric elastomer.

2 Doctorate of Engineering (DE) positions are available for Summer/Fall 2016 in Mechanical Engineering. The applicants are required to have master degree. The positions are directed by Multiscale Contact Mechanics and Tribology Laboratory and Optoelectronic Laboratory at Lamar University, Beaumont, TX, USA. Interested applicants may find more information at http://engineering.lamar.edu/mechanical/ and are encouraged to apply ASAP. 

     *** This is a NEW OPEN POSITION - not related to any previous post ***

The Center offers a unique fellowship program, where PhD students are co-supervised by one advisor from ETH Zurich and one from the MPI for Intelligent Systems in Tübingen and Stuttgart. PhD students are expected to take advantage of the opportunities offered by both organizations and to actively seek cross-group collaborations. All PhD fellows will register as graduate students at ETH Zurich and - upon successful completion of their PhD project - be granted a doctoral degree by ETH Zurich.
