摘要：
Crack resistance is an important characteristic of the structural strength of materials. The reliability criteria for articles depend upon it, i.e., 'safe damage' and 'safe life.' The first criterion is governed by the capacity of a material to provide article operation in the presence of cracks, and the second is governed by the time to generation of the first crack. Thus in order to evaluate crack resistance it is necessary to determine material resistance to crack generation and development. In this work resistance to crack generation and development is evaluated for wrought medium-strength aluminum alloys AMg6, AK4-1, and high-strength alloy V96ts which has a matrix (pseudo-single-phase) structure.
