摘要
本文将虚裂纹模型引入边界元法中,从而推出了用虚裂纹模型研究混凝土裂缝扩展过程的边界元法。由于边界元法在解决断裂问题时的优势,使得该法成为分析混凝土裂缝的有效方法之一。文中利用自编程序,给出了算例。
This paper deals with a numerical method-boundary element method-for propagating of crack in concrete with Fictitious Crack Model by taking fictitious crack model into boundary element
method. Because of its superiority for crack problem to other numerical methods boundary element method becomes a effective method for analyzing
concrete crack.
