hello,
i am trying to calculate a j integral values for a 3d crack in ansys.
i tried with a following txt code and as a input file.
the following code actully works for 2d crack for defined paths.what changes should be made to this for getting j-integral values in 3d crack?

Dear All,
I am using ANSYS 13.0 APDL to simulate a elastic model to calculate stress intensity factor. I got the solution successfully. However, I want to verify the answer with theoretical solution from crack analysis handbook. So I need to output the total force on a straightline.

Hi all,
I have a strange question that has puzzled me since last almost one year.
There are many SG-plasticity models in the technical literature, sometimes categorized as lower-order or higher-order models.
The problem is :
the constitutive models include the gradient of plastic parameters (e.g. plastic slip).
Hi,
I used abaqus 6.10 for analysing the an pressing opertion.
i gave the interation properties and other loading condition.
But, during the analysis, the die is penetrating inside the workpiece.
How can i overcome this.
With regards,

Dear All,
I am looking for some paper on material models for polymer nanocomposite
in high strain rate. I will be grateful if someone introduce me some good
paper.

Hi,
In my research i am trying to develop a new model for plastic deformation, and i suspect there is a strong similarity between
plasticity and turbulent flow !.
My question is: if there is workd done trying to apply Reynolds decomposition (Reynolds Stress) to the governing equations and solved plasticity problem in Solids?
thanks,
Yaron B.S.
Bistable structures, exemplified
by the Venus flytrap and slap bracelets, can switch between different
functional shapes upon actuation, and have important applications in
mechanical/electro-mechanical devices ranging from bio-inspired robots to
deployable aeroplane wings. Despite numerous efforts in modeling such large
deformation of shell structures, the roles of mechanical and nonlinear geometric
effects on bistability remains elusive. Closely related, emerging challenges
include modeling the spontaneous curving and buckling of thin objects such as
