Stress, Strain, and Deflection in Cracked C-Shaped Specimens
Abstract
Experimental strains and load-line deflections of C-shaped fracture- toughness test specimens are reported as functions of load and increasing crack depth. It is shown that the variation in strain at the outer surface may be used as an indicator of fatigue crack growth for evaluating the critical load in fracture toughness tests. The stresses and load-line deflections are compared with theoretical values calculated for the uncracked specimens. Their relation to the stress intensity factor of the cracked specimen is examined.
