AN EVALUATION OF CURRENT KNOWLEDGE OF THE MECHANICS OF BRITTLE FRACTURE

An explanation is given of the trend of results found in the many static model tests based on the concepts and some solutions of the mathematical theory of plasticity. Transition temperature, size effect, initiation and propagation of cracks are discussed qualitatively and on dimensional grounds. The conclusion is reached that future model tests should be made at the operating temperatures of the prototype and at stress levels encountered in practice if fundamental information is to be obtained. Load, energy, or appearance criteria for static or impact tests appear to be interpretable only in terms of such basic tests or information from the prototype. Each new material or variant of an existing one should be subjected to the basic tests before an acceptance test standard can be relied upon.
