The 3-dimensional finite element analysis was carried out for the compact normal and shear specimens made of the acrylic homogeneous material and the aluminum-acrylic dissimilar material subjected to mixed-mode loading. The 3-D local hybrid method based on an inverse problem was applied to evaluate the 3-D stress field using displacement data surrounded the crack tip of the surface of 3-D full model FEM. The error of stress intensity factor between the full model FEM and the local model hybrid method was discussed. The optimal hybrid domain size was discussed by changing the specimen thickness. Moreover, the optimal depth of the error evaluation was discussed to evaluate an equivalent nodal force by using displacement data obtained by the 2-D intelligent hybrid method.
