Abstract

A theory of fracture toughness is developed which is based on the Dugdale crack model. Work hardening is considered. By using the stress-strain curves as input data, K_Ic values are predicted for a wide range of materials including uranium alloys, beryllium, aluminum, a nickel-cobalt alloy, and a titanium alloy. The calculated values agree exceptionally well with the experimental values. Plastic-zone size (including a qualitative estimate of shape) and stress and strain in the plastic zone are also predicted.
