In this paper, the method for introduction of cohesive zone models to finite element models considering symmetric conditions was investigated. In order to fulfill the conditions, constrained conditions for nodes of interface elements, fracture toughness, and penalty stiffness should be appropriately given. Constrained conditions are determined so that only mode I deformation is occurred. In addition, fracture toughness and penalty stiffness are set to half and double of actual values, respectively. The method was verified through damage propagation analyses for two-kinds of models including 3-point bending beam and DCB test specimen.
