Does strain cause a change in volume?
Yes, strain can cause a change in volume. Strain refers to the deformation of a material in response to an applied stress, which can result in elongation, compression, or shear. Depending on the material and the type of strain, this deformation may lead to a change in volume, particularly in compressible materials. Inelastic materials may experience permanent volume changes, while elastic materials return to their original volume once the stress is removed.
Why gas molecules are elastic?
Gas molecules are elastic because they possess kinetic energy, allowing them to move and collide with other molecules. When gas molecules collide with each other or with the walls of their container, they transfer energy back and forth, resulting in elastic collisions that maintain constant pressure and volume within the gas.
Why gas molecules are perfectly elastic?
Gas molecules are perfectly elastic because they do not lose any kinetic energy when they collide with each other or the walls of their container. This means that their total energy remains constant, leading to elastic collisions. Additionally, gas molecules are considered point masses with negligible volume, contributing to their elastic behavior.
Cohensive energy derivation?
Cohesive energy is the energy required to completely separate a solid into its individual atoms or molecules. It is a measure of the strength of the intermolecular forces holding the solid together and is related to the bond strength between the atoms or molecules in the solid. Cohesive energy is typically expressed in units of energy per mole or energy per unit volume.
What causes rocks to undergo stress?
Stress is the force per area, which has the same units as pressure. An elastic material's response to stress is called the strain which is the change in its dimensions divided by its original dimension, such as a change in length divided by length, or change in volume divided by volume. It is a fundamental law that the stress is proportional to the strain, with the proportionality constant being the elastic modulus of the material, Young's modulus for change in length or the the compressibility for change in volume. For shear forces, the modulus is called the shear modulus and the strain is the deformation in the direction of the force divided by the distance from the fixed base that the forces is exerted.

What is strain energy due to torsion?
Strain energy due to torsion is the energy stored in a material when it is twisted under a torque load. It is calculated as the integral of shear stress and strain over the volume of the material. This energy represents the ability of the material to deform plastically under torsional loading.
What is the Derivation of element stiffness matrix?
The derivation of the element stiffness matrix in finite element analysis begins with formulating the potential energy of a system, typically through the principle of minimum potential energy or the principle of virtual work. By considering a linear elastic material under small deformations, the stiffness matrix is derived from the relationship between nodal forces and displacements, represented mathematically as ( {F} = [K]{u} ), where ([K]) is the stiffness matrix. The matrix is constructed by integrating the strain-displacement relationships over the element's volume and applying appropriate shape functions. Ultimately, this yields a matrix that relates the elemental nodal displacements to the internal forces within the element.

How do you find modulus of resilience?
Resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading. The modulus of resilience is defined as the maximum energy that can be absorbed per unit volume without creating a permanent distortion.It can be calculated by integrating the stress-strain curve from zero to the elastic limit. In uniaxial tension,whereUr is the modulus of resilience,σy is the yield strength,andE is the Young's modulus.
Why gas molecules are perfectly elastic?
Gas molecules are perfectly elastic because they do not lose any kinetic energy when they collide with each other or the walls of their container. This means that their total energy remains constant, leading to elastic collisions. Additionally, gas molecules are considered point masses with negligible volume, contributing to their elastic behavior.
What is the relationship between volume strain and the deformation of a material under stress?
Volume strain refers to the change in volume of a material when it is subjected to stress. When a material is deformed under stress, it can experience volume strain, which is the result of the material's particles moving closer together or farther apart. The relationship between volume strain and deformation is that as the material deforms, its volume may change due to the stress applied to it.
