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:

From venation of leaves to the blood and lymph vessels and tracheae of insects, 3D filamentous branching networks are a common pattern in all higher organisms.  These busy “highways” supply the tissue with nutrition and oxygen, expel waste and heat, as well as conduct immune reactions and other signal pathways. These microvascular networks are also essential for effective response of external stimuli in some sensitive plants, such as Venus flytrap and Mimosa pudica.
