Material Failures and their Relation to Component Design: A discussion of types of failure experienced in some main engine components and the design problems involved

THIS Note discusses the types of failure to be expected of some main engine components and the problems of avoiding such failure in new designs. Examples are given of the shortcomings of some design practices and in the current presentation of material property data. The need is stressed for more research in these areas to enable true safety factors to be predicted from a knowledge of the state of stress and the appropriate material property.
