资源简介：
The modelling of crack propagation for elastic-plastic materials is
critical in various engineering applications, such as safety analysis of
concrete structures and stability analysis of rock slopes. Combined with
elastic-plastic theory and fracture mechanics, the local radial basis
point Interpolation method (LRPIM)has the ability to analyse crack
propagation in elastic-plastic materials. Crack propagation in
elastic-plastic materials is compared using the LRPIM and Extended Finite
Element method (XFEM). The comparative investigation indicates that: (1)
The LRPIM results are close to the model test results, which indicates
that it is feasible for analysing crack growth of elastic-plastic
materials. (2) Compared with the LRPIM, the XFEM results are closer to the
experimental results, showing that the XFEM has higher accuracy and
computational efficiency. (3) Compared with the XFEM, when the LRPIM
method is used to analyse crack propagation, the propagation path is not
smooth enough, which can be explained that the crack tip stress and strain
not being accurate enough.
