Original Abstract
The paper describes a method for the identification of mechanical fracture parameters of fine-grained brittle matrix composites. An identification procedure utilizes the results of fracture tests, artificial intelligence methods, and nonlinear finite element-based analysis. Fracture properties of fine-grained brittle matrix composites are typically evaluated from the response of a notched prismatic specimen with a nominal depth of 40 mm tested in a three-point bending configuration. The aim is to identify parameters for the various composite mixtures and to feed material models for the deterministic and stochastic simulations of the quasi-brittle/ductile response of structures made of studied materials.
