Poblem in mdelling composite material in Abaqus
I can model uni-directional Composites in Abaqus/CAE but in bidirectional fibers I have problem with it! I'm not sure what can I do?

how to get the pressure value inside the cohesive element
I build a water inject model with COH3D8RP element, in the simulation, I can get the pore pressure value around the cohesive element, but I can't the value inside the cohesive element. the pore pressure changed around the cohesive element because of the pressure inside the cohesive element changes, however, I can't get the value of pressure inside the cohesive element.
Anyone can help, pls!
Efficient preconditioner for Augmented Lagrangian

Hi folks !
I have a question which is more mathematical than mechanical. However since it is to solve mechanical problem, one of you may have an answer !
I want to solve a non-linear problem with non-linear equality constrains and I'm using a augmented Lagrangian with a penalty regularization term that, as well known, spoils the condition number of my linearized systems (at each Newton iteration I mean). The bigger the penalty term, the worse the condition number is. Would someone know an efficient way to get rid of this bad conditioning in that specific case ?
LsDyna Displacement analysis
Hi FEA analysts
Could anyone please explain how to extract force for displacement method
in FEanalysis using hypermesh preprocessor, lsprepost and lsdyna solver
Managing Risk
Managing risk can be effectively done with the right software tools. Specifically with enterprise risk management software tools. In mechanical engineering projects, managing such risk is paramount to success and meeting deadlines. Most mechanical engineering students will not study such processes, but in having knowledge of managing risk, you will put yourself on a higher pedestal.

Hello every body
is there any modoule in the abaqus for modeling continuum damage mechanics under creep condition?
FGM modeling
Hellow
I am a graduate student on mechanic and I am working on the vibration
of FGM plate.
I try to model the FGM plate with Abaqus, so I need to use the UMAT
Subroutine
I don’t have big knowledge about Subroutine under Abaqus
Especially FGM materials
I’ll be thankful if some people give some guide lines about this problem.

Computational Study of Cortical Bone Screw Pullout using the Extended Finite Element Method (XFEM) - 2012
In this study, using a UDMGINI subroutine, stress components relative to a predefined osteon orientation were computed and an anisotropic damage criterion was used to determine damage initiation and to predict crack propagation.
ABAQUS embedded regions

Hello,
I am trying to find out if someone has information about the "embedded region" constraint in Abaqus. I am trying to model a very simple short fiber in a matrix (short cylinder inside a block). The model is purely elastic. The problem is, no matter how high I assign the values of the E modulus of fiber, I always get equivalent properties of composite (fiber + matrix) equal to matrix properties.
Interaction definition between axisymmetric shell element with soil element
Hi,
I was wondering if you have any idea that how can I define the surface-to-surface interaction betwee axisymmetric shell element(SAX1) and soil element(CAX4p).
