### Abstract

The simulation of crack propagation using combination of geometry crack model and random crack length based on finite element analysis with adaptive mesh is successfully developed. A computer code which was written with Fortran-90 programming language is developed for the purpose. All calculation process during simulation is performed automatically, no user decision need in this case. Geometry crack propagation model developed in this work allows the crack to propagate without any pre-determine direction. For each stage of crack propagation, the length of is determined randomly by the program. Two approaches have been used to determine crack length randomly i.e. maximum stress point and average crack length. Simulation result shows that the geometry crack propagation model has successfully simulated crack propagation process either under mode I or mixed mode I-II. The result shows that under mixed mode I-II, different crack lengths produce a different crack propagation path. The implementation of program developed in this work shows that model developed in this work produce a similar crack path propagation compared to the experimental as well as the previous researcher.
