| Abstract | ||||
| ABSTRACT Solid mechanics investigators gave the dynamics of bodies in impact special interest long time ago. Many approaches were developed to solve this problem since F. Neumann (1885). Reviewing these various approaches revealed that the impact body usually regarded as a system possessing one degree of freedom and the aim is to seek the configuration of maximum compression when the body starts to achieve instantaneous equilibrium. This paper is aimed to model the impacted body as a system possessing multi degrees of freedom by using the finite element method. The normal and oblique impacts are discussed taking into consideration the neighborhood area of the instantaneous impact point is smooth or rough. The effect of the number of elastic modes of vibration on the impact response is considered. | ||||
