摘要
介绍了ANSYS中1/4奇异单元的构造,采用1/4奇异单元进行了算例计算,并将结果与解析解作了对比,分析了该奇异单元的精度与应用范围,得出了采用奇异单元进行断裂分析的特性。
Based on the finite element theory,the paper introduces the 1 /4 singular element calculation in ANSYS,undertakes the comparison between results and analytical solution,analyzes the accuracy and applied scopes of the singular elemnt,and concludes the features for the crack analysis of the singular element.
