Shape And Size

Fracture properties of softwood under mode I loading perpendicular to the grain are studied in this paper. The stress intensity factor KIC in the R and L directions is measured by the compact tension test using small several specimens. The shape and size of plastic zone in crack tip is determined by numerical simulations based on von Hill yield criterion. The results show that anisotropic material constants do not affect the length of plastic zone along crack direction and it only operates on the plastic zone with θcr≠ 0. Strength ratios α1, α2 and toughness ratios r1, r2, influencing on the plastic zone, are discussed. Comparative analysis shows that r1 and r2 work markedly on the shape and size of plastic zone, whereas α1, α2 do less.

Abstract The objective of this study is to investigate the use of compact tension specimen calibration curves for evaluation data of fracture properties measurement performed on modified compact tension specimen made from cement based composites. From literature, the well-known calibration curve for compact tension specimen is compared with calibration curves for Modified compact tension specimen that are obtained from numerical calculation. The obtained results are quantified and accuracy of solution is discussed. The suggested curves could be preferably used for determining of the fracture parameters.
