Just finishing your PhD and looking for an exciting project that involves hyperelasticity and optimization applied to the design of soft robotics? Have a look at this 2-year postdoc position at the Technical University of Denmark (DTU):
Dear mechanics community,
I would like to draw your attention to our recent publication about the opensource finite element framework GetFEM:
https://dl.acm.org/doi/10.1145/3412849
In the paper, we describe a high level assembly language, available in GetFEM, which allows the user to easily create multiphysics models by providing mathematical expressions that are linearized and translated into a corresponding finite element model automatically. Among the many available applications to contact and solid mechanics problems, including finite strain plasticity, damage, homogenization, and topology optimization, the paper includes two representative examples:
1) Inflation of a hyperelastic membrane (implemented in only ca. 110 lines of code incl. meshing and post-processing)
2) Phase-field modelling of hydrogen assisted crack propagation (implemented in only ca. 160 lines of code incl. meshing and post-processing)
The full Python codes for the two examples from the paper are provided for the intrigued reader in the attached files below.
More information can be found on the software website: http://www.getfem.org/
and code for many more modeling examples can be found within GetFEM's source, e.g. http://git.savannah.nongnu.org/cgit/getfem.git/tree/contrib
Best regards

A 3-year PhD position in Micromechanics of White Etching Cracks is available at the Technical University of Denmark (DTU). More details about the project ideally starting during the spring of 2018 can be found at:
http://www.mek.dtu.dk/om-os/ledige-stillinger/job?id=b222a684-13d2-484f-...
Interested candidates with background in fracture and computational mechanics are invited to apply through the online application form found in the link provided above. Application deadline is January 7.
Two PhD openings in Shape and Topology Optimization are available at DTU. ( http://www.mek.dtu.dk/om-os/ledige-stillinger/job?id=dd7a97b4-827c-4838-... )
The two research topics concern structural designs optimized for buckling resistance and postbuckling behavior, respectively.
The PhD positions involve significant coding tasks, making previous programming experience in the finite-element method highly desirable.
Ideal project start is early 2018 and interested candidates are invited to apply through the available online application form.
