摘要
以承受均匀表面压力的中心穿透裂纹三维板为例,运用ANSYS有限元软件,使用KCALC命令和J积分方法计算其应力强度因子,并与解析解进行比较,结果具有相当高的精度,为三维构件裂纹扩展分析提供数值依据。
Taking the three-dimensional plate of center penetration crack of under uniform surface pressure as an example,using KCALC command and J integration method in finite element software ANSYS,it calculates the stress intensity factor.Compared with the analytical solutions,the results have quite high accuracy.This conclusion will provide numerical basis for crack propagation analysis of three-dimensional component.
