In the previous two chapters, we established the theoretical fundamentals for the study and analysis of the micro- and macromechanical properties of materials. We have discussed physical quantities such as elastic modulus, elastic limit, and yield strength. These physical quantities are called the basic mechanical properties of a material and include the mechanical properties under tension, compression, torsion, bending, and shearing. These basic physical quantities must be fully understood in the development, production, and application of a material. These properties are primarily measured through the appropriate mechanical test. For example, the tensile test can be used to determine many important mechanical properties such as elasticity, strength, plasticity, strain hardening, and toughness https://www.w3.org/1998/Math/MathML"> [ 1,2 ] https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429073649/180424e8-0a43-4d0f-a81d-b14fda7c69bb/content/eq1226.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> . Beginning with the tensile properties of a material, this chapter introduces the basic mechanical properties under tension, compression, torsion, and bending [3-6] at room temperature in the atmosphere and the corresponding experimental tests to measure these mechanical properties [7].
