MODEL ADJUSTMENT IN ABAQUS

[Oluwakay]

Hello Everyone,
Thank you for always helping out. I have a question. How can model a quarter of a bullet instead of a full geometry so as to reduce the computational time? I am interested to impact a certain portion of the target and i have a small size of it. How do i go about it?

...in other words, how can I run just a quarter of a bullet instead of the full one?

 

[FEA way]

Cut the bullet and the target with extruded cut operation. Then add symmetry BCs.

Thank you for your feedback. I have the option of "extrude cut" but I don't know how to go about it. It asks me to select the plane for the extrude cut. How do I create these planes please?

 

[FEA way]

It can be a datum plane (created before with one of the several available methods) or a face of the existing geometry.
