einen Gastvortrag über das Thema

A criterion for crack initiation at corners - single and mixed-mode loading

Der Vortrag findet im Hörsaal 2210 A im Gebäude 35 auf dem Campus der Universität der Bundeswehr München in Neubiberg statt.

Abstrakt

The failure criterion of Leguillon at reentrant corners in brittle elastic materials, validated for mode I loading, is being extended to mixed mode loading and is being validated by experimental observations. We present an explicit derivation of all quantities involved in the computation of the failure criterion. The failure criterion is validated by predicting the critical load and crack initiation angle of specimens under mixed mode loading and a comparison to experimental observations on PMMA (polymer) and Macoor (ceramic) V-notched specimens.
