I am performing a thermal stress analysis of composites. I need to verfiy the results with an existing paper. The variation of the thermal force resultants, Nx, Ny, and Nxy, of the plate along the y direction . I would like to know how to obtain the same with abaqus.
We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.
If this is of interest, please feel free to view the paper here.
I'm working on a Multibody dynamics code using the finite element method to simulate the behaviour of flexible beams (using this paper if anyone is interested/ it is relevant). I'd like to model joints, and as I only need spherical friction free joints I believe this should be easy using Lagrange multipliers.
When I run the code, the two bodies part company immediately. Any ideas where I'm going wrong? I'm just simulating a double pendulum with 10 elements in each body for now.

A PhD scholarship is available at DTU Mechanical Engineering, Section for Solid Mechanics, in the field of fatigue and wear in rolling and sliding contacts, with focus on computational stress and damage modelling. The department has well-established research activities in this field. The present scholarship is partly funded by the Danish Centre for Knowledge based Engineering for Improved Reliability of Critical Wind turbine Components (REWIND) supported by the Danish Agency for Science, Technology and Innovation.
