Applications of Local Mesh Refinement to Crack Propagation Simulation in Concrete Structures

In using finite element method to analyze concrete cracking,the difficulties are how to choose the mesh to meet the precision of calculation.For this reason,a local mesh refinement technique was presented.According to the precision requirement and the lacation of concrete cracking,the raw mesh was locally refined and incompatible mesh algorithm was used.Two examples showed that the local refined mesh technique was reasonable and substantial.
