— In this study, an optimized method to simulate the
dynamic 3D event of the impact of a rod with a flat surface
has been presented. Unlike the 2D FEM based contact
models, in this study both the bodies undergoing the impact
are considered elastic(deformable) and simulation is the
dynamic event of the impact, instead of predefined 2D
symmetric contact analysis. Prominent contact models and
plasticity models to define material properties in ANSYS
are reviewed. Experimentation results of normal and
oblique impact of the rod for different rods provided the
coefficient of restitution. Experimental results of
permanent deformation on the base for different impact
velocity is derived out of a prominent impact study. The
simulation results are in co-relation with experiment and
both indentation and flattening models on the coefficient of
restitution (COR) and permanent deformation of the base
and rod after the impact. Thus, the presented 3D Explicit
Dynamic simulation of impact is validated to analyze the
impact behavior of the 2 bodies without any predefined
assumptions with respect to boundary conditions or
material properties.
