摘要：
We propose a method for the assessment of the fracture toughness of structural materials and their welded joints under conditions of single dynamic loading, which is based on the criterion of nonlinear fracture mechanics δcrD. The regularities of the loading rate effect defined by the parameter δ' (the rate of the crack tip opening displacement) on the fracture toughness have been established. A procedure is recommended for prevention of fracture of welded structure elements under conditions of high strain-rate deformation.
