MATHEMATICAL MODELING OF IMPACT INTERACTION BETWEEN MULTI-STEP HETEROGENEOUS ROD AND RIGID OBSTACLE
We carry out here the mathematical modeling of longitudinal central elastic impact of heterogeneous rod system against rigid obstacle in the presence of unconstrained links. The rod system includes the multi-step heterogeneous rod and homogeneous rod contacting with the rigid obstacle. The links between the rigid obstacle and these rods are unconstrained; the homogeneous sections of this rod system have different lengths and cross-sectional areas
