| 151-0353-00L | Mechanics of Composite Materials | 4 credits | 2V + 1U | G. Kress, P. Ermanni | |
| Abstract | Modelling of stiffness and strength of fiber-reinforced plastics and laminates made thereof as well as simple structures is considered. For free-edge effects and periodic structures numerically efficient FEM approaches for generalized plane strain and unit-cell modelling are explained. Finally, the mechanical interpretation of experimental measurement results is treated. | ||||
| Learning objective | The objective is to impart understanding of the mechanical response of structures made from anisotropic and heterogeneous fiber-reinforced composite materials with all the peculiarities which are not known from metals. The course shall incite fascination with the multifaceted and exciting modelling questions in this field, providing a basis for research. On the other hand the course provides qualification for composite-materials product development within an industrial environment. | ||||

| 151-0360-00L | Procedures for the Analysis of Structures | 4 credits | 2V + 1U | G. Kress | |
| Abstract | Basic theories for structure integrity calculations are presented with focus on strength, stability, fatigue and elasto-plastic structural analysis. Theories and models for one dimesional and planar structures are presented based on energy theorems. | ||||
| Learning objective | Basic principles applied in structural mechanics. Introduction to the theories of planar structures. Development of an understanding of the relationship between material properties, structural theories and design criteria. | ||||
| Content | 1. Basic problem of continuum mechanics and energy principles: structural theories, homogenization theories; finite elements; fracture mechanics. 2.Structural theories for planar structures and stability: plane-stress, plate theory, buckling of plates (non-linear plate theory). 3.Strength of material theories and material properties: ductile behaviour, plasticity, von Mises, Tresca, principal stress criterion; brittle behaviour; viscoplastic behaviour, creep resistance. 4. Structural design: fatigue and dynamic structural analysis. | ||||
