刚体与弹性半空间正向碰撞界面应力脉冲特征
Study on interface stress pulse characteristics of a rigid body and elastic half space normal collision
摘要
Abstract
An analysis was made to study the characteristics of the interface stress pulse when the lateral surface of an infinite cylinder is normally collided with an elastic half space. Based on the physical and geometrical parameters of the cylinder, contact interface and the elastic half space, the motion equation of cylinder was established. The motion state parameters of the cylinder were obtained. The stress pulse expressions of the interface as well as the particle element of the interface were derived, and the characteristics of stress pulse were revealed. The research results are useful for the study of the stress of the collision interface with finite boundaries.关键词
