Effect of Crack Size on INitiation and Growth Behavior in a Particulate Composite Material

摘要

An important engineering problem in structural design is evaluating the strength and reliability of the structure. It is well known that the strength of a structure may be degraded during the period of its design life under service loads. One of the common causes of strength degradation is the result of the development of cracks in the structure. However, the development of cracks in a structure does not necessarily mean that the service life of the structure is terminated. Therefore, to determine the ultimate strength or the ultimate service life of a structure, studies should be conducted to determine the significance of flaw types and size as well as the rate of growth.
