high i am a student doing a project on curvature effect on thoracic stent. I want to curve the nitinol stent in abaqus. I am using RSURFU and doing static analysis. But am not able to curve it. Also when using implicit dynamic analysis with quasi static apllication my KE is high and comparable to IE. So can any body help me. Crimping and expansion is not a problem.

Good mourning, i am using Abaqus software to inverstigate a crack propagation problem using Abaqus, in this regards i have created a seam crack iner the geometrie which is a plate  under a plane stress condition, my problem is how to mesh around the crack tip in order to have a regular mesh around the crack tip so i can evaluate J integral for multiple contours, the Abaqus documentation mention the swept meshing technique but i coudn't find something about a 2D problem since the sweapt meshing technique nead to mesh a section and swept it over the rest of the body, and in 2d problem we

I have modeled a pile which was made to penetrate at a constant rate (Displacement controlled loading) into the soil. The steps were divided into geostatic, contact and Applied load steps. After the program runs successfully, i am facing difficulty in extracting the results.

 I want to plot the load vs. displacement curve at the bottom of the pile.  After i have summed up all the nodal forces at the bottom of the pile, the total load was coming quite less as compared to the applied Load/Displacement.

How to differentiate between the analysis of a "hollow pile with closed top and an open end" with "vented top and open ended pile".

After applying compressive load at both the pile tops (closed and vented), i have obtained/observed that the vented pile is offering higher resistance to penetration as compared to closed top pile.
