Learning Goals:

• Knowledge of models of real material behavior
• Ability to analyze the mechanical behavior and the deformation mechanisms of the individual material groups

Content Description:

• Structure of materials: metals, ceramics and polymers
• Elastic behavior: stress and strain, atomic interactions, HOOKE's law, temperature dependence of the elastic modulus
• Plasticity and failure: technical and true elongation, stress-strain diagrams, plasticity theory, hardness, material failure
• Fracture mechanics: linear-elastic fracture mechanics, flow fracture mechanics
• Mechanical behavior of metals: dislocations, overcoming obstacles, strengthening mechanisms, twinning
• Mechanical behavior of ceramics: crack propagation, static fracture mechanics, methods to increase strength
• Mechanical behavior of polymers: time-dependent deformation, elastic and plastic behavior
• Mechanical behavior of fiber composite materials: reinforcement, elasticity, plasticity and cracks, examples
• Material fatigue: types of stress, fatigue failure of metals, ceramics, polymers and fiber composite materials, fatigue strength
• Creep
