Originální abstrakt

The paper presents the description of the developed JAVA implementation of the semianalytical fracture model based on cracked hinge approach by Ulfkjaer et al (1995) and introduces generalization of the model formulation to enable using the tensile softening function with an arbitrary shape for the nonlinear part of the model assumed as cohesive crack. Performed simulations of an adopted wedge-splitting test show consistency of the new formulation with reference data. A comparison withh FEM solution is also presented to demonstrate a dependency of a load-crack mouth opening curve obtained by FEM and the implemented hinge model on its band width for different choices of softening function.
