Using Monte Carlo Methods to Compute the Uncertainty of Fracture Toughness and Fracture Resistance Curves

Abstract
The uncertainty of fracture toughness and associated fracture resistance curves for single edge-notched tension (SE(T) or SENT) specimens is a key component missing from widely accepted testing protocols. Complicating matters, these uncertainties are not easily calculated using traditional propagation-of-error techniques. Uncertainty estimates using Monte Carlo techniques for two test methods are presented and the effect of changing the distribution and tolerance specified for the measurement and input quantities on the results is investigated.Citation
