An empirical investigation of different procedures was carried out for determining a lower bound fracture toughness on the basis of small specimen test data in the ductile-to-brittle transition range. The procedures have been applied to various data sets in order to study the practicability and behaviour of the different procedures. It has been shown that these procedures produce estimates which fall into the lower tail regime of the scatter band of fracture toughness. Within the range of the… CONTINUE READING
