Design development and Operational test are performed appropriately during the every stage for development of aircraft structures. Design development test includes the basic material properties test and component certification test and Operational test is to verify performance of the all composed system. The element of material properties test are based on the ASTM method, but for the certification test of components a few methods are applied according to the level of technology.
Composites materials for Carbon fiber and Glass fiber are evaluated in the Tension-Tension fatigue test and fatigue fracture surfaces of the materials is shown. Concept of Safe-Life is reviewed as mean stress is dominant effect on the structures when applying Miner's damage rule. Damage Tolerance design is reviewed in the test and evaluation as of Willenborg's crack retardation model typically and discussed shutoff ratio of the model. Finally a simulation result of the model is shown for the special case of structures by using the example of AFGROW S/W.
