Mechanical Properties of Engineering Materials: Relevance in Design and Manufacturing

The chapter provides an introduction to mechanical engineering, covering fundamental concepts of mechanical properties of materials and their use in the design and manufacturing. It first explains the notion of mechanical properties of materials and then elaborates on the proper definition of most relevant properties as well as materials testing to obtain these properties. The role of mechanical properties at the design stage in form of the design criterion is explained. The use of material properties to assess equivalent stress and strain in complex loading conditions is revealed. At the manufacturing stage, the notion of additive (material is added to the workpiece), neutral (the volume of the workpiece is preserved), and substantive (the volume of the workpiece is reduced) processes is introduced. The relevant properties of materials in the neutral (forming) and substantive (cutting) processes are considered.
