Compact Tension Test

The paper is focused on the determination of mechanical fracture parameters from the modified compact tension test applied to the cement-based composites. The experimental measurement was carried out by means of the ARAMIS equipment. The numerical study is performed by ATENA 2D software (based on a cohesive law for crack propagation) taking the material parameters for numerical study from the standard compression test. The experimental and numerical results are discussed and compared with the help of basic fracture parameters and Load – COD (crack open displacement) diagrams.

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.
