Sažetak
Experimental analysis of fracture of a centrally notched panel under tension in the large-scale yielding regime is presented in this paper. The aluminium alloy specimens were puled in a screw-driven tensile-testing machine with a slow cross-head speed until collapse in order to determine material resistance to crack propagation. Stable crack extension was measured by using crack-gages and the fracture process was recorded by a digital video camera. Using video record, the critical crack tip opening displacement value, associated with stable fracture onset was estimated. The fracture test and the obtained critical CTOD value enabled determination of critical J-integral value using a finite element simulation program.
