Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

When I simulated the beam with shell element, first I define reference points at both end of the beam and assign 'RIGID BODY/PIN OR TIE' to  nodes at the edge,after that I applied bending moments and boundary conditions to both reference points.  But after I finished the buckling analysis, the result is not reasonable,the eigen value is about two times the the value I expected.

Every has his own knowledge.

Hi,

I am working on a 3D contact problem where a spherical part is pressed against another spherical surface. I was wondering what variables may be interesting to study for this problem. I decided to look at the contact area CAREA, the contact pressure CPRESS and the stress S but I am not able to find how Abaqus defines and calculates these variables, does anyone know?

Thanks

Hi there! I am really new to Abaqus and I need to model a composite
laminated crash cone under impact to a flat solid wall (analytical
surface is used). I modelled a cone with a layers of conventional shell
elements with hashin failure criteria and surface-based cohesive
behaviour as interaction between layers representing the interface of
composite laminates. The model runs successfully but once I checked the
energy balance, the damage dissipation energy from the cohesive, it
turned out to be NEGATIVE (I think this is wrong).

Hi all,

I am trying to model a solder joint in double lap shear. I am using the Modified Anand's Model. But for some reasons the analysis is not completing and does not gives any errors as well. Since I am new to abaqus, I am not able to solve this. Here is my input file:
