Thank you very much for your suggestions. I will try to model the whole structure as a 3D. The place in ABAQUS manual where it is stated is ABAQUS Analysis User's Manual( version 6.5) Section 19.4.3: Defining distributed surface loads on plane stress elements.

Hello, I am trying to model a large deformation plane stress problem, where pressure is applied at the edges of a plate. According to ABAQUS manual in order to take into account changes in thickness with deformation I need to use three-dimensional elements at the edge. But I cannot find the way...

There are two reasons I am running nonlinear analysis: 1) I am interested in large deformations, therefore nonlinear analysis should be on and 2)I am interested in constitutive response of an inhomogeneous plate (neo-hookean material models hyperelastic material response) Because of the second...

Yes, it is rectangular.

Thank you very much for all your replies. I don't have any holes or cracks in my plate. Initially, I tried to run analysis for heterogeneous plate - it didn't work. Then I started to simplify my model and finally came to a simple homogeneous plate under uniaxial tension. I should say that...

I didn't think about buckling problem, although Abaqus always reports negative eigenvalues. You must be right. But the plate is not under compressive loads - it is stretched. I have never heard about buckling of a stretched plate. Can that happen? Thank you.

I am trying to run nonlinear analysis (hyperelasticity) in Abaqus under uniform traction boundary conditions. I need to find the maximum extension I can get using Abaqus for this type of problem. I found that Abaqus can handle this problem till some specific value of the pressure magnitude and...

Thanks for the reply. The thing is that I am not considering plasticity - it is a purely elastic problem.
