000015192 520__ $$2eng$$aIn the frame of nuclear safety research program of the french ‘Institut de Radioprotection et de Sˆuret´e Nucl´eaire’ (IRSN), a micromechanical approach is developed to predict the fracture of concrete containment structures in nuclear power plants. A problem in studying crack propagation within these structures is the computational cost related to spatial discretization of each relevant scale. A way to reduce the computational cost without any significant loss of accuracy is to perform local adaptive refinement. The refinement method presented in this paper is called CHARMS, and is based on the splitting of elements in a region of interest of an existing mesh. This refinement method is applied to the recent ‘Eigen-Erosion’ method allowing crack propagation based on a killing element-type method with respect to the Griffith’s criterion.
