摘要
基于有限元和断裂理论,利用有限元软件ANSYS分析了车辆动静荷载对含裂缝道路结构体的作用,在ANSYS中对裂尖环向设置奇异单元,将车辆荷载简化为线源荷载,分别分析了静荷载和动荷载作用下Ⅰ形应力强度因子的变化规律。
Based on the finite element and abruption theory, the function of cracked road structure tender the vehicle load was analyzed with finite element software ANSYS. The singular element to crack tip toroidal settled in ANSYS and simplified vehicle load as linear load, the variation regularity of Ⅰ -typed stress intensity factor under static and movable load were analyzed.
