摘要
A bilinear cohesive law analyzes the in-plane nominal strength of Quasi-brittle material containing a single hole in which damage around the open hole is represented by a line crack loaded on its faces. This analysis of quasi-brittle structures has been done by taking into account the geometry and length of fracture processing zone and the shape of the cohesive law. The nominal strength based on size effect is analyzed for similarly shape specimen geometry. Simple design tables for the bilinear cohesive law have been developed respect to the specimen types offering a very useful for engineering designers.
