Abstract
Notch sensitivity diagrams are numerically derived for tensile specimens of linearly softening materials, exhibiting tensile fracture. The notch types are center crack, single and double edge notch, and center hole. Computations are based on Finite Element modeling of the specimen geometry and the Damage Zone Model (DZM) for the linear softening fracture process and static strength prediction. The diagrams are presented in a non-dimensional format, representing failures ranging from linear elastic fracture to net section failure at the ultimate strength level. Furthermore, the diagrams reveal the effect of the notch and specimen size, and the stiffness, fracture energy and strength of the material.
