Abaqus low velocity impact

[vikram manoj]

i am modelling low velocity impact on composite plate with 8 layers. To reduce the simulation time I am considering q quarter model with two symmetry boundary conditions in x and y directional and fixed in other side. I am using a rigid impactor with some mass and velocity, my doubt is should I consider total mass of the impactor or 1/4 th mass of the impactor since i am taking only 1/4th model of composite plate.

 

[FEA way]

Only quarter of the impactor’s mass since that’s what its geometry represents in your model.

Whenever somebody suggests using symmetry in FEA I suggest they trade off computational time vs human fuck up time.
