Experimental Study of Near-Crack-Tip Deformation Fields

Source

Stationary crack-tip singularity fields of strain-hardening material, Al 2024-0, are investigated by combined moiré and moiré interferometry techniques as a crack goes through elastic and plastic deformation. The experimental results are compared with the corresponding theories at different stages, K field and HRR field, respectively. A two-dimensional finite element computation is also carried out at plastic deformation stage to aid the analysis.
