	Objectives
	THE STUDENT WILL LEARN THE DESIGN ASPECTS OF MECHANICAL COMPONENTS, WITH PARTICULAR REFERENCE TO THE METALLIC MATERIAL RESISTANCE, IN ORDER TO ASSESS THE COMPONENT SIZING AND MAKE A FAILURE DIAGNOSIS. HE WILL GAIN KNOWLEDGE ON LOW CYCLE UNIAXIAL FATIGUE, HIGH CYCLE MULTIAXIAL FATIGUE, FRACTURE MECHANICS, PLASTICITY AND CREEP. HE WILL LEARN HOW TO LEVERAGE ON NUMERICAL TOOLS FOR THE STRESS ANALYSIS CALCULATIONS WITH PARTICULAR REFERENCE TO THE FINITE ELEMENT METHOD (FEM).
