抄録

In order to estimate the crack initiation behavior at the corners of square inclusion and square hole in rubber material by fracture mechanics, a static tension test is carried out. The direction and load for the crack initiation are measured. The finite element analysis of the stress distribution in the vicinity of the corner point is also performed. By the consideration based on the concept of the linear fracture mechanics, it is found that the direction of the crack initiation is estimated by the maximum value of the governing component of a stress σ_θ for the singular stress field near the corner. It is also found that the initiation load is characterized by a stress singularity order and a parameter K^* which govern the stress field near the singular point.
