Salzbrenner, T. Crenshaw] The effect of experimental technique on the measurement of elastic-plastic fracture toughness has been investigated. Multiple-specimenJ-integral measurements have been performed at an intermediate loading rate. One set of measurements was conducted completely under computer/servohydraulic control, while another set was performed with a fixture that mechanically limits the maximum displacement and load. For the single condition tested, a minimal effect was measured on the initiation fracture toughness. An increased effect was seen on the measured crack-growth-resistance (J-R) curve as the amount of crack growth increased. The consequences of such testing methods in terms of general (intermediate loading rate) testing will be discussed. Society for Experimental Mechanics, Inc., 1990 Salzbrenner R.
