Together with Ondřej Rokoš and Milan Jirásek, we are searching for a postdoctoral researcher to work with us on leveraging quasi-continuum methods towards robust simulations of initiation and propagation of instabilities in architectured materials and flexible mechanical metamaterials. Eligible candidates must hold a Ph.D. degree awarded in 2015 or later.

Hi 

 

I have different 3D models of laminates where I analyse the delamination propagation using zero thickness cohesive elements in Abaqus/Standard. My experience with the RIKS solver and Newton solvers are that they are extremely sensitive to even small changes in the step size settings as well as other solver settings.
