When a cylindrical object is subjected to a twisting force, it experiences torsion. The torsional modulus of elasticity, also known as the shear modulus or modulus of rigidity, is a measure of a material’s resistance to twisting and shear deformation under torsional stress. This key material property is essential for engineers and researchers working with…
Steel tensile test provides key data on strength, ductility, and additional mechanical properties for structural design and quality control. Steel is one of the most widely used construction materials in buildings, vehicles, infrastructure, and machinery due to its immense strength and durability properties. Steel exhibits immense strength thanks to advanced production methods. However, validating mechanical…
Elastic materials are substances that can stretch or deform when a force is applied, but then return to their original shape once the force is removed. These materials have the useful property of elasticity, which enables them to undergo reversible deformation. Some common examples of elastic materials include rubber bands, bungee cords, stretchy fabrics like…
Hooke’s law is a principle in physics that states that the force needed to extend or compress a spring is proportional to the extension or compression of the spring from its resting position. This law has several important applications in engineering, especially civil and mechanical engineering. This linear relationship between force and displacement holds only…
The shear modulus of steel, denoted G, is a fundamental mechanical property dictating the elastic shear behavior of solid materials like structural steel. As opposed to Young’s modulus which measures resistance to normal strains, the shear modulus of steel quantifies stiffness under pure transverse shearing loads. An accurate value is essential for modeling the precise…
Elasticity is a key mechanical property that all civil engineers must understand. Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically. When external forces are applied to a material…
