Summary:
Tests of five medium- and high-strength steels were used to investigate some prospective simplifications in JIc test and data analysis procedures. Three-point bend specimens with material strengths of 500 to 1500 MPa and a nominal thickness of 10 mm were tested at room temperature. The investigation included: (1) JIc tests using measured crack-mouth displacement to calculate load-line displacement based on an expression that relates the two displace ments; (2) a simple zero-point adjustment for J versus ?a curves, whereby certain intermediate ?a values are shifted to the blunting line to correct for errors at low values of ?a; (3) a comparison of ?a and JIc results from the load-drop method, which gives a simple measure of crack growth after maximum load, with results from the usual unloading compliance method
