contact

Hello,



I'm trying to figure out how the Interaction Module (surface-to-surface contact) in ABAQUS works. I want to apply a compression force on a 2D axisymmetric

deformable body via an analytical rigid surface(2D and axisymmetric also) - basic stuff. When I launch my simulations,

I get the good strains and stresses at the surface of the body which is in contact with the analytical rigid. Moreover, the reaction

forces and displacement of the analytical surface are adequate.

Hi,

I am trying to analysis a model in ABAQUS with a plate bolted to the Bracket top surface at 4 ends. I have to define contact between them (and also bolted at 4 ends) to get the Modal frequency. But When I searched for it, I got the answer that contact doesn't work with Modal analysis as contact is a nonliner problem and Modal Analysis only solves linear problem.

Hi there,

I'm using SPH in LS-DYNA as my tool to simulate the projectile penetrate the box. Both projectile and box are modeled as sph. 

I'm having problem to determine the suitable contact of these two entity.

Could someone please help me... any tips that will help me to tackle this problem is highly appreciated!

Thanks... 

Dear all,

In my FE model (pin on disc), I would like to define a contact property between pin and disc with a friction defination available in ABAQUS. I have assumed that friction coefficient depends on parameters like slip rate, pressure and temperature only. When i used friction coefficients with slip rate and pressure, model works without any error but if i use friction coefficients with slip rate, pressure and temperature, the model doesn't work and come up with following errors;
