What is Strength of Materials?




Strength of materials, also known as mechanics of materials, is a branch of applied mechanics that studies the behavior of solid bodies under various types of forces and loads. It aims to determine the internal stresses, strains, deformations, and displacements that occur in the bodies due to the external forces and loads. It also aims to design the bodies such that they can resist the external forces and loads without failure.


Definition and Scope




A solid body is a material that has a definite shape and size. It can be classified into two types: isotropic and anisotropic. An isotropic body is a body that has the same properties in all directions. An anisotropic body is a body that has different properties in different directions.


A force is a push or pull that acts on a body. It can be classified into two types: concentrated and distributed. A concentrated force is a force that acts at a single point on a body. A distributed force is a force that acts over a surface or a volume of a body.


A load is a force or a combination of forces that act on a body. It can be classified into two types: static and dynamic. A static load is a load that does not change with time. A dynamic load is a load that changes with time.


The scope of strength of materials includes the following topics:


  • Simple stress and simple strain



  • Torsion



  • Shear and moment in beams



  • Beam deflections



  • Continuous beams



  • Combined stresses



  • Columns



  • Thin-walled pressure vessels



  • Thermal stresses



  • Energy methods



  • Elastic stability



  • Theories of failure



  • Plastic deformation



  • Buckling of plates



  • Stress concentration



  • Fatigue and fracture



Basic Concepts and Principles




The basic concepts and principles of strength of materials are as follows:


  • Stress: Stress is the intensity of force per unit area. It is denoted by $\sigma$ (sigma) and measured in units of pressure, such as pascals (Pa) or pounds per square inch (psi). There are different types of stress, such as normal stress, shear stress, bending stress, torsional stress, etc.



  • Strain: Strain is the measure of deformation or change in shape or size due to stress. It is denoted by $\epsilon$ (epsilon) and measured in units of dimensionless ratio, such as percent (%) or radians (rad). There are different types of strain, such as normal strain, shear strain, angular strain, etc.



  • Elasticity: Elasticity is the property of a material that enables it to return to its original shape and size after the removal of stress. A material that exhibits elasticity is called an elastic material. The degree of elasticity depends on the elastic modulus or coefficient of elasticity, which is the ratio of stress to strain for a given material.



  • Plasticity: Plasticity is the property of a material that enables it to undergo permanent deformation or change in shape or size after the removal of stress. A material that exhibits plasticity is called a plastic material. The degree of plasticity depends on the yield strength or yield point, which is the maximum stress that a material can withstand without undergoing plastic deformation.



  • Torsion: Torsion is the twisting or rotation of a shaft or a member due to an applied torque or moment. Torque is the product of force and perpendicular distance from the axis of rotation. Moment is the product of force and perpendicular distance from a point or a line. Torsion causes shear stress and shear strain in the shaft or the member.



  • Shear: Shear is the sliding or cutting action of two parallel forces acting in opposite directions on a body. Shear causes shear stress and shear strain in the body.



```html or a member due to an applied transverse load or moment. Transverse load is a load that acts perpendicular to the longitudinal axis of the beam or the member. Moment is the product of force and perpendicular distance from a point or a line. Bending causes normal stress and normal strain in the beam or the member.


  • Deflection: Deflection is the displacement or change in position of a point or a line on a beam or a member due to bending. Deflection depends on the geometry, material, and loading of the beam or the member.



  • Continuous beams: Continuous beams are beams that are supported by more than two supports. Continuous beams have different reactions and moments at each support due to the continuity condition.



  • Combined stresses: Combined stresses are stresses that result from the combination of two or more types of stresses, such as axial stress, bending stress, shear stress, torsional stress, etc. Combined stresses can be resolved into principal stresses and maximum shear stresses using Mohr's circle or other methods.



  • Columns: Columns are long and slender members that are subjected to compressive loads along their axes. Columns can fail due to buckling or instability, which is the sudden lateral deflection of the column due to a small increase in the load. The critical load or buckling load of a column depends on its length, cross-section, material, and end conditions.



  • Thin-walled pressure vessels: Thin-walled pressure vessels are cylindrical or spherical shells that are subjected to internal or external pressure. Thin-walled pressure vessels can be assumed to have negligible thickness compared to their radius. Thin-walled pressure vessels experience hoop stress and longitudinal stress due to the pressure.



  • Thermal stresses: Thermal stresses are stresses that result from the expansion or contraction of a body due to a change in temperature. Thermal stresses depend on the coefficient of thermal expansion, which is the fractional change in length per unit change in temperature for a given material.



  • Energy methods: Energy methods are methods that use the concepts of work and energy to analyze the deformation and stability of structures. Energy methods include strain energy, work done by external forces, work done by internal forces, potential energy, kinetic energy, etc.



  • Elastic stability: Elastic stability is the ability of a structure to return to its original configuration after the removal of a load that causes instability or buckling. Elastic stability depends on the stiffness and geometry of the structure.



  • Theories of failure: Theories of failure are criteria that determine whether a material will fail or not under a given state of stress. Theories of failure include maximum normal stress theory, maximum shear stress theory, maximum normal strain theory, maximum shear strain theory, maximum distortion energy theory, maximum strain energy theory, etc.



  • Plastic deformation: Plastic deformation is the permanent deformation or change in shape or size of a material after the removal of stress that exceeds its yield point. Plastic deformation depends on the flow curve or stress-strain curve of the material.



  • Buckling of plates: Buckling of plates is the phenomenon of sudden lateral deflection of thin flat plates due to compressive loads acting on their edges. Buckling of plates depends on the geometry, material, boundary conditions, and loading of the plates.



  • Stress concentration: Stress concentration is the phenomenon of localized increase in stress near a discontinuity or irregularity in a body. Discontinuities or irregularities include holes, notches, cracks, fillets, etc. Stress concentration can be reduced by using stress relief features such as chamfers, grooves, etc.



  • Fatigue and fracture: Fatigue and fracture are modes of failure that occur due to repeated or cyclic loading. Fatigue is the progressive weakening or cracking of a material due to cyclic loading below its ultimate strength. Fracture is the complete separation or breaking of a material due to loading above its ultimate strength.
