Hi Everybody, 

I'm using Mohr-Coulomb with Cohesion Hardening  in Abaqus and I'm wondering how can I postprocess the state of Cohesion in the field?



Tanks ahead,

Dear all,

Could anyone help to give me some advice on how to implement a kind of nonlinear interaction relevant to relative velocity in ABAQUS? The interaction force has a quadratic function with the relative velocity between two nodes. Thanks.

Hi all,

How to check normals for 3D elements in abaqus 6.11

when all the inclusions with similar shape are embeded into the matrix, the 
 Mori_Tanaka effective Stiffiness/Compliance Tensor can be , respectively, given by

L ={∑c_r(L₀^*+L_r)^-1}^-1-L₀^*

M={∑c_r(M₀^*+M_r)^-1}^-1-M₀^* 

where,

Can anyone show me  the
 positive definiteness of the Stress Polarization Tensor  P_ijkl, i.e.,

τ_ij^* P_ijkl τ_kl^*≥o,

and further, 

τ_ij^* M_ijkl τ_kl^*≥τ_ij^* P_ijkl τ_kl^*,

Dear
Colleagues & Friends:

International Journal of Computational Materials Science and Engineering (IJCMSE) is a
quarterly journal which aims to promote international exchange of new knowledge
and recent developments in all aspects of computational materials science and
engineering. By this means, we would like to invite you to contribute to IJCMSE
with your forthcoming research manuscripts.

Dear colleagues,

I kindly ask for advice on the following problem:

I simulate the uniaxial compression of a heterogeneous cylinder representing bone. Thus, it is not the visible solid exterior rim of the bone, but represents a porous structure within the bone, so-called trabecular bone, see the figure underneath.

The simulation is done in ABAQUS. The sample contains 164175 elements of type C3D4. The heterogeneous, porous structure makes it impossible to use axisymmmetric elements. The constitutive behavior is ELASTIC.

hi all,

        i am very new to abaqus and i want to simualte sliding wear between a pin and a disc. i found from the literature that by using user subroutines we can calculate the wear. i am not getting how to use a user subroutine , can any one expain how to use user subroutines in the CAE. is there any simple example problems in understanding this user subroutine functions. thanks in advance.
