dc.description.abstract |
Comparative study for determining the KR-curves associated with the cohesive stress distribution
for complete fracture process for two standard specimen geometries i.e., three-point bending test and
compact tension test specimen geometries of concrete using analytical method and weight function approach
is reported in the paper. The laboratory size specimen (100 ≤ D ≤ 400mm) with initial-notch length/depth
ratios 0.3 and 0.5 are considered in the investigation. The load-crack opening displacement curves for these
specimens are obtained using well known version of Fictitious Crack Model (FCM). It is found from the
numerical results that the weight function method improves computational efficiency without any appreciable
error. The stability analysis on the KR-curves and the influence of specimen geometry and the sizeeffect
on the KR-curves, the CTOD-curves and the process zone length during crack propagation of complete
fracture process are also described. |
