摘要
由于数学上的困难,文献中有关等腰三角形截面杆弯曲问题只有在一些特殊情况下获得了精确解。本文所研究的应力函数可以用来解决所有顶角在0°<2α<90°范围内的等腰三角形截面杆弯曲问题的精确解。Timoshenko关于等边三角形截面杆弯曲问题的应力函数及其解是本文给出的普遍应力函数及其解中的一个特例。
Because of the difficult mathematics involved, exact solution for the problem of isosceles triangular bars in bending have been carried out only in specific cases. The stress function to be presented in this paper is applicable for all values of 2a between 0 deg and 90 deg. Timoshenko's stress function and solution may be viewed as a special ease of this general stress function and solution.
