Learning outcomes: To know: - nature of elastic, inelastic and plastic deformations, fatigue and creep of materials; - types and mechanisms of fracture; - influence of internal (chemical composition, structure) and external (temperature, stress, strain rate, environment) factors on the deformation behavior of materials; - solutions to fracture-related problems; - methods, equipment, and applications of mechanical testing. Be able: - to apply this knowledge in simple design problems and assesment of product failure risks; - to predict the deformation behavior of materials under operating conditions; - to identify and analyze fracture surfaces; - to determine the mechanical properties of materials; - to interpret data and/or test results in terms of material mechanical properties.
