摘要
研究自由边界的矩形截面梁在自由端和对称中面分别受到质量块横向撞击后的刚-塑性动力响应,通过完全解分析、结合数值方法给出梁的瞬态变形,并讨论输入能量、质量比等参数对梁的最终变形、移行铰消失位置及能量耗散的影响。
In this paper,the rigidperfectly,plastic dynamic response of a freefree beam subjected to impact by a projectile at the free end and the midspan crosssection is presented.The influence of some parameters such as input energy and mass ratio on the final deflection,travelling plastic hinge position and energy partitioning of the beam are discussed.
