First of all i guess the right question is difference between strain and deformation. Actually the strain is deformation in a material over its original length. So strain is a relative quantity while deformation is simply change in length, hence absolute and is new length minus original length.
Strain= deformation(L2-L1)/original length(L1)
By Deformation.
The resistance to stress-induced strain is called "stiffness." Stiffness measures how much an object deforms under an applied load, reflecting its ability to resist deformation. In materials science, this is often quantified by the modulus of elasticity, which indicates the relationship between stress (force per unit area) and strain (deformation) in a material.
Modulus strength, often referred to as the modulus of elasticity or elastic modulus, is a measure of a material's stiffness or resistance to deformation under stress. It quantifies the relationship between stress (force per unit area) and strain (deformation) in the elastic region of the material's stress-strain curve. A higher modulus strength indicates that a material is stiffer and deforms less when subjected to an applied load. Common types of modulus include Young's modulus, shear modulus, and bulk modulus, each describing different modes of deformation.
Volumetric strain of a deformed body is defined as the ratio of the change in volume of the body to the deformation to its original volume. If V is the original volum and dV the change in volume occurred due to the deformation, the volumetric strain ev induced is given by ev =dV/V Consider a uniform rectangular bar of length l, breadth b and depth d as shown in figure. Its volume V is given by, This means that volumetric strain of a deformed body is the sum of the linear strains in three mutually perpendicular directions.
Stress is the load per unit area acting within a material. It can be thought of as the internal resistive response of a material to an externally applied pressure.Strain is the change in shape of an object in response to external pressure or internal stress. To complicate matters, strain causes the transmission of stress through an object (as in simple terms the strain causes an internal "movement" causing one part of the inside of an object to press against the material next to it generating stress in this region, this in turn can cause more strain and so on!).There are a number of differing types of strain, for example axial strain is defined as the change in length relative to the original length of an object (e.g. a steel wire being stretched). This change in shape is also called deformation. Volumetric strain occurs when an object is squashed or pulled on all sides leading to a change in volume.
The relationship between viscosity and strain in materials under deformation is that viscosity is a measure of a material's resistance to flow, while strain is the amount of deformation a material undergoes when subjected to stress. In general, materials with higher viscosity tend to exhibit less strain under deformation, as they are more resistant to flow and deformation. Conversely, materials with lower viscosity are more likely to experience higher levels of strain when deformed, as they flow more easily.
The normal strain is a deformation caused by normal forces such as Tension or Compression that act perpendicular to the cross-sectional area, while the shear strain is a deformation obtained from forces acting parallel or tangential to the cross-sectional area.
The stress vs strain equation, also known as Hooke's Law, is used to determine the relationship between the applied force and resulting deformation in a material. It is expressed as stress E strain, where stress is the force applied to the material, strain is the resulting deformation, and E is the material's Young's Modulus, which represents its stiffness.
The stress vs strain formula is used to calculate the relationship between the applied force and resulting deformation in a material. It is expressed as stress force/area and strain change in length/original length.
To calculate plastic strain in a material under deformation, you can use the formula: Plastic Strain Total Strain - Elastic Strain. Plastic strain is the permanent deformation that occurs in a material after it has exceeded its elastic limit. It is important to consider when analyzing the behavior of materials under stress.
By Deformation.
The relationship between stress and strain in materials under mechanical deformation is described by Hooke's Law, which states that stress is directly proportional to strain. This means that as a material is subjected to a force (stress), it will deform (strain) in a predictable and linear manner. The relationship between stress and strain helps engineers and scientists understand how materials behave under different conditions and can be used to predict their mechanical properties.
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.
The equation that relates strain to stress in a material under deformation is known as Hooke's Law, which is expressed as stress Young's Modulus strain.
The formula to calculate total strain is: Total Strain Elastic Strain Plastic Strain. Elastic strain is the initial deformation of the material under load, while plastic strain is the permanent deformation after the material reaches its yield point.
