How to find stress and strain in a material under load?
To find stress and strain in a material under load, you can use the formulas: stress force applied / cross-sectional area of the material, and strain change in length / original length of the material. These calculations help determine how the material deforms under the applied load.
How to find strain from stress in a material?
To find strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Young's Modulus is a measure of the stiffness of a material. By dividing the stress applied to the material by its Young's Modulus, you can calculate the resulting strain.
How can one determine the shear strain in a material by finding shear strain?
To determine the shear strain in a material, you can find the shear strain by dividing the displacement of the material parallel to the shearing force by the original length of the material. This calculation helps quantify how much the material deforms under shear stress.
How to find the proportional limit on a stress-strain graph?
To find the proportional limit on a stress-strain graph, locate the point where the graph transitions from a straight line to a curve. This point represents the maximum stress at which the material behaves elastically, meaning it returns to its original shape after the stress is removed.
How to find the modulus of elasticity in a material?
To find the modulus of elasticity in a material, you can conduct a test called a tensile test. This test involves applying a controlled amount of force to a sample of the material and measuring how much it deforms. The modulus of elasticity is then calculated by dividing the stress (force applied) by the strain (deformation). This value represents the material's ability to deform under stress and return to its original shape.

How to calculate strain energy in a material?
To calculate strain energy in a material, you can use the formula: Strain Energy 0.5 x Stress x Strain. Stress is the force applied to the material, and strain is the resulting deformation. Multiply stress and strain, then divide by 2 to find the strain energy.

Find an expression for the energy density in terms of stress and strain?
The expression for the energy density in terms of stress and strain can be expressed as ρe.
How do you find modulus of elasticity from load-displacement curve?
The modulus of elasticity is a property specific to a given material and in practice is derived through laboratory testing. The modulus of elasticity is defined as stress/strain. One would have to apply a force uniformly over a known cross section of a material and monitor the strain utilising strain gauges. When the results are plotted you will notice that you get elastic behaviour up to a point of yield (this is known as the yield stress in normal carbon steels, however in stainless steel where the yield point is not as defined, we normally accept it to be the 0.2% strain) and the material should behave linearly in this area. If you take the gradient of the stress/strain, this will be your Elastic modulus. Please note that the plotted curve will begin to flatten off roughly at the 0.2% strain line and this is due to the fact that the material has yielded. even after this point the material will not fail but will act 'plastically' up to a point where the material fractures which we call the ultimate stress.
How do you calculate the Youngs modulus of a material?
To find the Young's modulus of steel or any other material you require a plot of it's deformation response to loading. Specifically it's axial stress vs axial strain. From this you need to find the gradient of the straight line portion of the curve where the material is behaving elastically and obeying Hooke's law. This is essentially stress / strain and gives you Young's modulus.
How do you find the loss factor in hysteretic damping?
Loss factor is best obtained by dynamically loading (extensional, torsional etc.) a specimen of the material and plotting the hysteresis curve in stress-vs strain plane. If the total area under the hysteresis loop is D, the loss factor is computed from the following formula Loss factor=D/(2*pi*max stress* max strain) For lightly damped materials, loss factor is just twice the daming factor 'zeta' which obtained either by log-decrement method or half-power bandwidth method.

Find the yield strength from a stress-strain graph?
Follow the graph's positive slope (across the first quadrant) until the graph is no longer linear. The yield strength is determined to be the last point (with concern given to the stress value) on the linear section. After this point the graph is irregular because the material has failed to a point of no return and can no longer handle the load (stress).
