内容記述 |
Error index for stress intensityfactor(SIF)obtained from the results of finite element analysis(FEA)using singular elements was developed by taking advantage of the facts that the functional shape of displacement solution around a crack tip is known and that the SIF can be evaluated only by the displacements. The error index has a dimension of SIF and converges to zero when the actual error of SIF by displacement correlation technique converges to zero. Finite element analyses were carried out for some typical crack problems, including a mixed mode crack, whose analytical solutions are known and the validity of the index was concretely demonstrated through the comparison between the variations of error and index with the sizes of singular element. The degree of error seems to be justly estimated through the value of index. |
