TY - JOUR AU - AB - An approximate procedure is presented which allows a ductile fracture analysis to be performed with a single fracture toughness value measured at maximum load in a small-scale test. This maximum load toughness value is used to predict an R-curve which is then used to predict maximum stress and crack extension. Predictions from this approach are compared with experimental data from 20 wide-plate specimens made from various ductile materials. A limited number of these specimens are also analyzed using experimental R-curves in order to investigate the effect of the assumed shape of the R-curve on predictions. In addition, an analysis is presented which allows one to determine the critical tearing modulus required for a structure to exhibit collapse controlled failure. Potential applications of these analyses are discussed.
