摘要
The residual strength of a material can be defined as the strength in the presence of a crack like flaw. These flaws will occur in all engineering structures sooner or later. It is important to know the consequences of these flaws with respect to the integrity of the structure. The tool to make quantitative predictions of the residual strength are provided by models under the denominator of fracture mechanics. For monolithic materials fairly good models are available and are currently being used by the industry. In hybrid materials like Fibre Metal Laminates (ARALL and GLARE), monolithic and composite materials are present, leading to a different fracture behaviour. It is the question whether fracture mechanics models developed for metals can be used for FML's. With the use of Centre Cracked Specimens it is shown that an invariant R-curve can be generated for the investigated FML's GLARE 2 and GLARE 3. In this paper, the results and methods are shown in respect tot the fracture behaviour of FML's.
