本文研究受静力预加载的弹性结构在冲击载荷下的屈曲问题。文中导出了临界载荷的计算公式。作为应用,还研究了受静力预加载的浅拱,一端支座突然沉陷时的冲击屈曲,给出了临界载荷值。
This paper studies the buckling of elastic structures subjected to static preload under impact loading. The formula for calculating the critical load is derived in this paper. As an application, the impact buckling of a shallow arch preloaded under static preloading and sudden collapse of one end bearing was also studied, and the critical load value was given.
