Hi,



I am working with a finite element code implemented in C++ in my research group. Recentl I implemneted an incompressible finite strain element.

 Currently I am making use of verification tests to check whether my element runs accurately for various hyperelastic strain-energy models. I have succesfully completed a verification test using the Mooney-rivlin strain-energy density function. However, I have been unable to find verification/benchmark tests which I may use to test other strain-energy density functions.

Hello everyone,

 Basically I am using ABAQUS/Explicit to perform quasi-static analyses on steel members reinforced with cfrp strips. I have obtained the cohesive zone model parameters and I am trying to apply them to my model. I am assuming that failure will occur in the adhesive, as observed experimentally.

Hi all,

       I am new to ANSYS. My problem is how to connect (transistion) different elements like solid-shell or solid-beam elements, because the different elements have different degrees of freedom and at the interface the mismatch of degrees of freedom occurs. Its basically, what are transition elements present in ANSYS and how to use them

thank you 

 I am using XFEM in ABAQUS to simulate crack growth from one material to another. Although the crack passes through the interface, the simulation stops after crack growth of few more elements with this error:

"THE FRACTURE CRITERION f=1.5400 AT ELEMENT 2469, THE DAMAGE INITIATION TOLERANCE HAS BEEN EXCEEDED AND CUTBACK IS REQUIRED."

 This element is the one right next to the crack front.

 I have tried to increase the damage initiation tolerance > 0.5 and the crack grows one more element and then same error.
