Abstract | The course introduces general methods for the analysis of stress and deformation states in mechanical parts, as needed to optimize their design and to ensure their mechanical integrity. Starting from the derivation of the basic problem, the concepts are extended to consider anisotropic materials, plasticity, viscoelasticity and viscoplasticity. Examples of engineering applications are discussed. | ||||||||||||||||||||||||||||||||
Learning objective | The students will be able to analyse mechanical problems, to formulate and apply design criteria involving strength, local plastification, plastic collaps, fatigue and creep. They will understand how mechanical theories are derived from basic principles as well as the role of phenomenological models. They will learn different representations of the deformation behaviour of engineering materials and the implications for the assessment of products’ function and mechanical damage. They will know how to use advanced mathematical tools to solve engineering problems. | ||||||||||||||||||||||||||||||||
