Current test methods used in establishing materials selection and design parameters to avoid brittle fractures can be categorized into (1) the transition temperature approach and (2) the fracture concepts approach. The main features, the advantages and the applicability of some examples of each approach are discussed. The need to consider the effects of material strength level, fracture initiation versus propagation behaviors, specimen and defect dimensions, and plastic deformation on the test results and their relation to the selection of design parameters are indicated.
