Composite failure theory

WebMay 23, 2024 · Abstract. Failure of a composite structure under impact loads is often very complex due to the presence of many concurrent phenomena occurring during the event. For some fibres, such as … WebDescription: A complete and comprehensive theory of failure is developed for homogeneous and isotropic materials. The full range of materials types are covered from very ductile metals to extremely brittle glasses and minerals. Two failure properties suffice to predict the general failure conditions under all states of stress.
