I want to do research work in analysing composite using the ansys or similar software.I want to get the details regarding modelling the laminated composites.
And also details regarding analsing the properties of composite for cyclic load,fatique load,and torsion.
which ansys version is suitable
Dynamic Brittle Fracture as a Small Horizon Limit of Peridynamics
Overview: The peridynamic formulation is a
spatially nonlocal derivative free model for simulating problems of free crack
propagation.Material points interact through short-range forces and the
formulation allows for discontinuous deformations. Here the short-range forces
are initially elastic and soften beyond a critical relative displacement. We
upscale this peridynamic model to find the macroscopic (a.k.a. small horizon)
limit. It is shown that the limiting macroscopic evolution has bounded energy
given by the bulk and surface energies of brittle fracture mechanics. The
macroscopic evolution corresponds to the simultaneous evolution
of the fracture surface and linear elastic displacement away from the crack
Curvature effect on nitinol aortic stent
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.
J integrale evalution on Abaqus
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

ABAQUS Post processing
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.
ABAQUS Analysis
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.
