On the large structures such as ships's hull, tank structure, etc., various loads are acting. In some structural members, therefore, out-of-plane stress due to bending often may become larger than in-plane stress due to stretching. In this report, the characteristics of brittle fracture initiation of mild steel plate with a through crack under the combined action of stretching and plate bending have been studied both experimentally and theoretically using the linear elastic fracture mechanics (L.E.F.M.). As a result of the investigation, the following conclusions are obtained. (1) Effect of bending load on the characteristics of brittle fracture initiation can be evaluated over a fairly wide range by the criterion proposed by authors using the concept of energy balance based on L.E.F.M. (2) From the results of eccentrically loaded and center-notched Deep Notch Tests, it is extremely safe for design that the maximum surface stress is considered as the equivalent fracture stress at higher temperature than - 180 degrees. (3) The evaluation of fracture phenomena using the equivalent K-value proposed by authors is confirmed to be fairly good for expressing the behavior of the material such as mild steel plate.
