Determining multiple contact pairs in Abaqus explicit

Submitted by tuhinsinha.25 on

Hello,

I want to know that is there a novel way of defining several two dimensional contact pairs in Abaqus/Explicit. I know that abaqus has the capability of defining a general contact but it is restricted only to Abaqus standard and 3D Abaqus explicit problems. 

I have a 2D plane strain problem where I have to specify more than 1000 contact pairs in the assembly between similar instances of the same part. Is there a fortran subroutine that could be used to determine so many contact pairs?

 

Thanks,

Tuhin

Cohesive Zone Models are elasticity

Submitted by Roberto Ballarini on

I have always, and I believe correctly, considered cohesize/bridging models linear elasticity. This is because whether we apply them to holes or cracks, we are solving the equations of ELASTICITY, with nonlinear boundary conditions along the part(s) of the crack along which a traction-separation law is applied. So the material model is totally elastic. All we did was to augment the elasticity theory with an ad hoc physical condition (inspired by experiments such as Dugdale).

UMAT to VUMAT

Submitted by Mitsyeti on

 

Hello ,

 

I am a relatively new user to ABAQUS , and i am trying to figure out a way ( if there exists ) to convert a model defined in ABAQUS / Standard to Explicit for conducting impact testing.

 Now i have figured out most of the model apart from the material defination. The previous model has a User defined material , and i need to convert it to a VUMAT.
