One PhD position is currently available in the Department of Materials Science and Engineering at Monash University (Melbourne, Australia). The project aims to investigate the mechanical behaviour of hydrogels and will involve the development of novel constitutive theories as well as their implementation in a finite element code.
Candidates should have a strong background in solid mechanics, applied mathematics and programming.
Hello everyone
I am wondering how to insert the cohesive element between every two solid elements in Abaqus, such that each element can separate with others? Is there a tool can do this and generate Abaqus input file?
Thanks
Axially compressed bilaterally constrained columns, which can attain multiple snap-through buckling events in their elastic postbuckling response, can be used as energy concentrators and mechanical triggers to transform external quasi-static displacement input to local high-rate motions and excite vibration-based piezoelectric transducers for energy harvesting devices.
In this contribution, an elasto-viscoplastic constitutive model based on the single mode EGP (Eindhoven Glassy Polymer) model is proposed to describe the deformation behaviour of solid polymers subjected to finite deformations under different stress states. The material properties of the original model are determined and calibrated from a uniaxial compression-loading test. Then, several numerical examples under different stress states are presented to illustrate the limitations.

Dear all,
We have just published a research paper presenting, for the first time ever, a method for direct microscale mechanical testing of cement paste. We find this method very useful, and believe that it can provide a good basis for multi-scale modelling of cement and concrete materials.

Abstract:
The elastic Ericksen's problem consists of finding deformations in isotropic hyperelastic solids that can be maintained for arbitrary strain-energy density functions. In the compressible case, Ericksen showed that only homogeneous deformations are possible. Here, we solve the anelastic version of the same problem, that is we determine both the deformations and the eigenstrains such that a solution to the anelastic problem exists for arbitrary strain-energy density functions. Anelasticity is described by finite eigenstrains.
