摘 要:本文从弹性应变能变化的观点,采用复变函数理论的方法,给出了H.Liebowifz公式的另一数学证明。同时,也得出了Griffith能量变化修正公式。
Abstract: In this paper, using the method of the theory of a complex variable, we have given another mathematical proof of Liebowitz formula from a point of view of elastic strain energy change and have also obtained a corrective formula of Griffith energy change.
