Dear all I'm trying to simulate the cohesive contact between a deformable sphere and a rigid plane using cohesive surfaces The sphere is in a first step compressed against the surface. Thereafter, the sphere should be sheared along the surface until fracture of the cohesive surface To avoid...

Dear! I'm trying to model the bonding strength between two spherical particles using cohesive surfaces in ABAQUS 6.11 Firstly, the particles are pressed together using controlled displacement, giving a planar circular contact area, thereafter sheared apart (also with controlled displacement)...

Dear all, I'm studying the adhesion between elastic-plastic spherical particles by use of "surface based cohesive behavior" in Abaqus 6.9 and I'm now doing a parametric study on how the shape of the traction-separation law influences the results given that the surface energy remains the same...

Dear all The problem is know solved by changing to hybrid elements (CAX4H) and Node-to-Surface contact which I find a little bit strange because I thought that Surface-to-Surface contact was superior in almost all cases. The problem is know symmetric (to the last digit) for indentation depth...

mechfeeney: Of course, I apologize for that! I'm now trying with stricter convergence criteria to see if that reduces the problem. My hope is to simulate an indentation depth that is so large as 5 % of the particle radius /Erik

Thank you everyone for your help! rstupplebeen: The reason why I'm not modelling one sphere and a rigid plane is that when this "simple" case works, I will start with spheres of different radii and material. I put convert SDI on and it helped up to a time step of ~8E-2. mechfeeney: Thanks for...

Hi! I have a problem with modelling contact between two axi-symmetric spheres in ABAQUS v 6.10. The spheres have the same radii and the same material E = 455 GPa yield stress = 50 MPa Ideal plastic I know that the material is "extreme" but the purpose with it is to simulate fully ideally...
