MECHANICAL PROPERTIES OF MATERIALS
MECHANICAL PROPERTIES OF ENGINEERING MATERIALS The mechanical properties of materials describes the behavior of the material under the action of external forces. Mechanical properties play important role in material selection. (1) Strength: Definition- Ability of material to resist external forces or loads, without fracture. On the basis of type of stresses induced by loads, strengths are categorized as tensile strength, compressive strength, shear strength, Torsional strength, Yield strength and Ultimate tensile strength. Tensile strength- Ability of material to withstand (without fracture) tensile forces which causes Tensile Stress. Compressive strength- Ability of material to withstand (without fracture) compressive forces which causes Compressive Stress. Shear Strength- Ability of material to withstand (without fracture) Forces forces which causes Shear Stress. Yield Strength- The maximum stress at which noticeable elongation is seen without increase in load. Ultimate Tens
