Vliv T-napětí na přepočtové vztahy pro otevření v kořeni trhliny a J integrálu
Pavel Hutař, Zdeněk Knésl
pages 91 - +9p., full text

Relations between crack opening displacement (CTOD) and other fracture mechanics parameters are of a great importance in fracture mechanics. The basic aim of this paper is to describe an infiuence of T-stress on the plastic eta factors) plastic rotation factor and proporcional factor) i. e. the factors correlating J-integral and CTOD. Specimens with different values of T-stress (compact tension) three point bend and single edge cracked tension) are analysed by finite element method) the factors are calculated as functions of corresponding crack length and results obtained are discussed from the point of view of two-parameter fracture mechanics.
