| everal experimental and finite element methods were investigated with the objective to effectively model the collision between a composite softball bat and softballs of different COR and compression specifications. Experimental softball characterization methods included COR/CCOR, compression, dynamic stiffness and dynamic mechanical analysis testing. Experimental bat characterization methods included barrel compression and modal analysis. Finite element models were built in HyperMesh and analyzed in LS-DYNA to simulate the experimental results collected. Softballs were modeled using Material models... |
