Test Results from J-Integral Studies: An Attempt to Establish a Testing Procedure

Source

Test results from JIc studies are analyzed by a resistance curve technique. J values from bend type specimens containing a deep precrack are plotted as a function of crack extension measured from the specimen fracture surface. Using these plots a technique is suggested for establishing a JIc measurement point.

Data from an A216 steel are presented for describing this method of JIc analysis. In addition, JIc versus temperature data are presented to compare JIc with previous KIc results. Finally, a step-by-step procedure for measuring JIc is outlined.
