Hello, 

I want to ask things about the updation of local material coordinate in large deformation. 

Does there exist two ways for this?

1. Polar decomposition of Gradient Deformation Tensor F to get the rotation tensor.

2. Update each basis vector of local material coordinate system using modified Gradient Deformation Tensor F_bar = F*J^(-1/3).

What I cared about is the second method, is the second method available?

Wish someone could help me, : ). Thanks!! 

Hi all,

I have been trying to model the surface interaction between two blocks of material using surface-based cohesive elements (*cohesive behavior). This works well in ABAQUS CAE (standard) when I set the material properties as "Mechanical, Elastic" so no problem with that.

However, I would now like to use the material properties from a fortran code. To do this, I was planning on defining the elements using *UEL with an overlay to record all the values. Is this compatible with cohesive zone elements? 

Hi,

I am doing the beam tutorial in ABAQUS and I get the mises stress output as given in the tutorial document (ABAQUS manual appendix B).

I am trying to understand the S11, S22 and S33 outputs from this model. The document I am using for my steps are attached. Couldn't attach my .cae file here.

    I need someone who can help me with GTN model and it's vumat/umat specially, friends that have experiment pleaaaaase help me, thanks,regards

hi all

Am doing my project in abaqus. how to calculate the normal mode fracture energy, shear mode fracture energy first direction and shear mode fracture energy second direction in power law

could anyone help me???

thanks in advance...

I need pdf or video tutorials for modeling of beam column joint in ansys . please help me any one

I am a student using ansys for solve problems but i have a problem "how to find at which force value the component will be fail". A ball has to pass through a cone and i am intrested to know that force value at which boll will be pass through cone nerrow section while boll diameter is large than small dia of cone.

Plz help me anyone ansys masters

Thanks dear frnd & sir...
