Influence of constraint effect on transfereability of fracture mechanics characteristics
Vlček L., Kozák V.
pages 376 - +8p., full text

This paper presents the consideration on the change judgement of J integral and Q parameter as the base parameters of two-parameter elastic-plastic fracture mechanics. An extensive set of non-linear 3D FEM analyses of SE(B) specimens deals with crack front conditions, which are characterised in terms of J-Q trajectories. Results of numerical simulations provide "effective" thickness, which can be used in statistical approaches.
