Mechanische Wechselwirkungen an Werkstoffübergängen von Verbundkörpern aus ungleichartigen Werkstoffen. Teil II: Grundlagen zur Berechung von Spannungs- und Verformungszusänden

Mechanical Interactions at Material Transitions in Composite Bodies out of Dissimilar Materials. Part II: Basic Principles for the Calculation of Stress and Strain States . The different types of interfaces are defined with the help of the concepts of geometry and the material transitions occuring in them. Among other things, a possibility for exact quantitative definitions of continuous and discontinuous material transitions at the interface of bonded materials is given. The well-known error function, as well as the static and kinematic interface conditions, are made use of. These enable the establishment of quantitative expressions for the stress and strain states in composite bodies. The difference between the continuous and discontinuous type of material transition give rise to highly differing equations. The cylindrical composite bodies are at first considered. The special treatment of the composite bodies out of sheet and plate materials are discussed in a separate chapter. The “sufficient” interface conditions for the discontinuous material transitions in cylindrical, sheet and plate-composite bodies are further derived.
