By Ozbolt J., Reinhardt H.W.

Within the current paper, a finite point code in accordance with the microplane version for concrete is used for the research of general mixed-mode geometries: a Single-Edge-Notched beam, a Double-Edge-Notched specimen and a Dowel-Disk specimen. an area smeared fracture finite point research is conducted. As a regularization process, the crack band process is used. The significant goal of the learn used to be to enquire no matter if the smeared fracture finite aspect code is ready to are expecting mixed-mode fracture of concrete without optimisation of the fabric version parameters. comparability among experimental and numerical effects indicates that the used code predicts structural reaction and crack styles realistically for all circumstances investigated. furthermore, it really is proven that for many of the studied geometries a mixed-mode fracture mechanism dominates at crack initiation, in spite of the fact that, with elevate of the crack size mode-I fracture turns into dominant and the specimens ultimately failed in mode-I fracture.
