DISPLACEMENT FIELD ANALYSIS IN WEDGE SPLITTING TEST SPECIMEN BY ODM METHOD
Original language description
Multi-parameter fracture mechanics is nowadays quite extensively applied when cracked structures/specimens are investigated. The reason is that it has been shown that it can be helpful and bring more accurate results when fracture processes happen in a larger region around the crack tip, what can be typical for material like concrete or other materials with quasi-brittle behaviour. Various relative crack length configurations have been chosen in order to investigate the importance of the higher-order terms of the Williams power expansion on the crack-tip stress field distribution in Wedge splitting test specimen. The higher-order terms are calculated by means of the over-deterministic method from displacements of nodes around the crack tip obtained by a finite element analysis in different radial distances from the crack tip. The effect of the constraint level is investigated. Although the third and higher terms of the Williams series are very often neglected, their influence on the opening stress values is investigated.
