Elasticity: Stress-strain relationship

A rigid body seems to have a specific shape and size. But in reality, a rigid body can be compressed, elongated, or even bent. The suitable operation which can be carried out on a body depends upon its mechanical properties. Thus it can be concluded that rigid bodies can be deformed. The behaviour of a rigid […]

Introduction: Hooke’s law, also referred to as the law of elasticity, was developed by an English scientist Robert Hooke in 1660, the statement given was, the magnitude of deformation is directly proportional to the deforming force or load for relatively small deformations of an object.  When the load is removed, the item returns to its

When any material shows a linear relationship between stress and strain and exhibits elasticity in some form or the other, it is called linearly elastic material. For elastic materials, stress is directly proportional to strain, this means for small deformation, stress is directly proportional to strain. Therefore, in simple terms, As per Hooke’s law, the

Elasticity plays a crucial role in physics. In most cases, you will find various examples related to elasticity. You need to understand the matter or subject of elasticity with some examples. It is also essential to learn about the application of elastic behaviour to materials.  A better understanding of elasticity It is essential to understand

Young’s modulus is a word used to characterise a material’s capacity to bend. The Young modulus is a mechanical characteristic that indicates solid material’s tensile or compressive stiffness when a force is applied longitudinally. It is also known as the modulus of elasticity in tension or compression (i.e., negative tension). It is computed using the

Elasticity is the property of any material or substance getting stretched or compacted by external pressure. The applied pressure alters the shape or size of the material. When the pressure applied increases, the volume occupied by the material decreases, and pressure and volume are inversely proportional. The fluid elasticity or compressibility employs bulk modulus to

When the forces that caused the deformation are eliminated, elasticity refers to the ability of a distorted material body to return to its original shape and size. Elastic behaviour (or response) is a term used to describe a body that has this flexibility. Most solid materials exhibit elastic behaviour to some degree. Still, the size

When the atoms of a selected element are so far apart, each atom shows allowable energy levels.  Energy Bands in Solids in every particular element, the magnitude of the interaction of the neighbouring atom’s influence depends on the spacing and therefore the electron’s location inside the cluster of atoms. An energy band is a range

Electronic band structure (or simply band structure) in solid-state physics refers to the range of energy levels that electrons can have in a solid and the range of energies that they may not have. The quantum-mechanical wave functions permitted for electrons in a vast systematic lattice of an atom or molecule are examined using band

A polymer consists of large molecules or repetition of subunits held by weak or intermolecular solid forces. An elastomer is a type of Polymer in which the intermolecular forces binding the molecule together are weak. The weak intermolecular forces come with certain freedoms for the material. Rubber is an example of Elastomers. People often use
