English Title

Determination of Stress Intensity Factor Value for Chevron-Notched Specimens – Pilot Study

Type

Peer-reviewed article not indexed in WoS or Scopus

Original Abstract

The description of material behavior is one of important information for its application in civil engineering. One area is covering fracture mechanical properties. For evaluation of the fracture toughness values, the knowledge of calibration curve is important. The paper is aimed on the numerical modelling of the test specimens with a chevron notch serving as an initiator of the stress distribution at the crack tip. The three-point bending test configuration with a chevron notch is used for the simulation given by plane model with different layer width of cross section part and output is given by the value of the stress intensity factor KI for tension loading mode.
