Learning outcomes |
In this UC it is intended that the student structure the knowledge about the mechanical behaviour of materials, acquire the capacity of analysis and attitude of synthesis of that knowledge directed to design/dimensioning and learn concepts, characteristics and purposes of mechanical elements.
Analyse the mechanical behaviour of materials regarding stress and deformation, elastic and plastic behaviour, constitutive laws and resistance.
Establish concepts, purposes and characteristics of the components of mechanical systems in order to encompass aspects related to the operation, selection, design/dimensioning (static and fatigue), safety and reliability of mechanical equipment.
Design machine elements, supported by a methodology and procedures generally applied in the analysis of machine elements, mechanisms, machinery and structures.
