Multiple faculty positions in Mechanics and Materials at TU/e Eindhoven

Submitted by Marc Geers on Thu, 10/17/2019 - 13:18

There are several openings for faculty positions in the field of Mechanics and Materials in our Department of Mechanical Engineering of the Eindhoven University of Technology in The Netherlands. The department is seeking for outstanding faculty members at all levels and in particular the fields of Function integration in material systems and Development, optimization and behaviour of new advanced materials. At present, talented people with an experimental profile are strongly encouraged to apply.

Why getting trouble with Abaqus UMAT subroutine when using interaction features like contact or tie?

#ABAQUS

I am implementing a constitutive relation in UMAT subroutine using the commercial software Abaqus. First, I tested the UMAT subroutine with 'one element model' first. Then I tested with comparatively bigger geometry. It worked fine. Now when I am trying to do a models involving contact, i.e. use of the 'Interaction module'. I am getting error of over-constraint warning for 'Split Tension test of concrete cylinder'. The same input file (except the material definition) is running on Abaqus perfectly with Mohr-Coulomb criteria. I can see a reasonable stress and strain contour.

Contact stiffness of multiscale surfaces by truncation analysis

In this concise piece of work, an effective method is shown to gain new understandings into the role of surface structure in the field of contact mechanics. In particular, normal contact stiffness is correlated to parameters of surfaces' fractal dimension and amplitude.
