I'm working on the explicit simulation of needle insertion into a thermoplastic polyurethane foil (0.4mm thick) using a cohesive (orphan mesh elements) zone modeled between two parts of a phantom corresponding to the outer diameter of the needle tip. While using an intricate bevel needle, the...
I'm working on the simulation of needle penetration into a thermoplastic polyurethane foil (0.4mm thick) using cohesive interaction behavior between two parts of a phantom corresponding to the outer diameter of the cutting edges of the needle tip. As for the model, I'm using a symmetric model by...
Hello,
I am running a quasi-static analysis of medical needle penetration into a thermoplastic polyurethane material (0.4mm thick) using cohesive zone modeling in Abaqus Explicit solver.
The whole analysis will last for 3 seconds. The problem is that my stable time increment is very small. It...
