โฆ Synopsis
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,, 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.

The catalytic substance, the heating conditions, the order in which the materials are added to the container, the support, and the concentration of the solution, all exert a notable influence on the final presence of catalyst in the samples. Consequently, they may also affect (in a different manner)
