What is the difference between dynamic strain aging and strain aging?
Strain aging could be described as " normal wear and tear " or the fatigue that is experienced under normal conditions, whereas Dynamic strain would be an out of the normal range stress condition like a one time over stress condition where the sum of much strain aging is experienced in one " dynamic" occurrence.
Difference between unbonded strain gauge and bonded strain gauge?
The essential difference is that the bonded strain gauges are bonded on to the specimen whose strain is being measured whereas the unbonded strain gauges are not bonded on to the specimen. As the bonded strain gauges are well bonded on to the specimen, the entire strain being experienced by the specimen is transferred to the strain gauge. However, the bonded strain gauges are affected by temperature changes and also due to transverse strains.For transverse strains and ambient temperature compensations, suitable circuits for compensation can be used using Wheatstone's bridge. The unbonded strain gauges cannot transfer the strain of the specimen to the strain gauge and hence it is used mainly for displacement, or pressure or force transducers. It is least affected by transverse strain and temperature compensation of unbonded gauges cis automatically eliminated using Wheatstone's bridge.
What is the difference between E and nu in engineering geology?
E is generally taken to be the elastic constant known as Young's modulus which describes the relationship between axial stress and axial strain where Hooke's law still applies (i.e. linear elasticity). Nu is Poisson's ratio which is the relationship between axial strain and radial or transverse strain. For more information, please see the related link.
What is the deformation between strain and deformation?
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)

What is the relationship between engineering strain and percent elongation?
strain is percent elongation/100; for example a strain of 0.02 is 2% elongation. Often we refer to elongation at failure; for example if a material fails at 10% elongation its strain is 0.10
What is the stress strain and elongation of a wire if it is 80cm long and 0.03 cm in diameter used to hang an object weighing 6.5 x 10-2 Newton?
The stress is 0.065 newton, plus a component at each point that's due to the weight of the wire below that point. That component depends in turn on the density of the material of which the wire is formed. The strain and elongation both depend on the ductility of the material of which the wire is formed.

How do you find out elongation on a graph?
To find elongation on a graph, you need to identify the points where the graph reaches its maximum and minimum values within a specific interval. Elongation is typically represented as the difference between these two extreme points. You can calculate this by measuring the vertical distance between the highest peak and the lowest trough on the graph. Additionally, if the graph represents a periodic function, the elongation can be assessed by examining the amplitude of the oscillations.
What is the difference between MD Elongation and TD Elongation?
MD Elongation (Machine Direction Elongation) refers to the stretching or deformation of a material along the direction of its production or processing, typically along the length of a film or sheet. In contrast, TD Elongation (Transverse Direction Elongation) measures the stretching perpendicular to the machine direction, across the width of the material. These properties are crucial in evaluating the mechanical performance and flexibility of materials, especially in applications like packaging and textiles. Understanding both elongations helps in optimizing material performance for specific uses.
What is the elongation of a bar due to its own weight?
The elongation of a bar due to its own weight is the deformation or stretching that occurs in the bar when it is subjected to a gravitational force. This elongation can be calculated using the formula for axial strain: ΔL = (ρ * g * L^2) / (2 * E), where ΔL is the elongation, ρ is the density of the material, g is the acceleration due to gravity, L is the length of the bar, and E is the Young's modulus of the material.
How do you measure elongation on steel plate?
Elongation on steel plate is typically measured by marking a gauge length on the plate and then subjecting it to tension until it fractures. The elongation is calculated as the difference between the final length of the gauge section and the original length, expressed as a percentage of the original length. This test helps to determine the ductility and deformation capabilities of the steel plate.
What is the formula of modulus of elasticity?
The modulus of elasticity (also known as Young's modulus) is calculated using the formula E = stress/strain, where E is the modulus of elasticity, stress is the force applied per unit area, and strain is the resulting deformation or elongation.
The strain which causes a material to pull apart is known as?
The strain that causes a material to pull apart is known as tensile strain. It occurs when a material is subjected to tensile stress, leading to elongation or stretching. This type of strain is significant in engineering and materials science, as it helps determine a material's ability to withstand forces without failing.
What is difference between strain gauge and extensometer?
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
What do you notice about the strain gauge readings on opposite sides of the section?
The strain gauge readings on opposite sides of the section typically show opposite values, indicating tensile strain on one side and compressive strain on the other. This behavior is expected due to the bending or axial loading of the section, where one side experiences elongation while the other side contracts. The difference in readings helps in understanding the stress distribution and the overall structural response to applied loads. Such data is crucial for assessing the integrity and performance of engineering materials and structures.
