  • Elastic Modulus - Pavement Interactive

    The modulus of elasticity for a material is basically the slope of its stress-strain plot within the elastic range (as shown in Figure 1). Figure 2 shows a stress versus strain curve for steel. The initial straight-line portion of the curve is the elastic range for the steel. If the material is loaded to any value of stress in this part of the curve, it will return to its original shape. Thus ...

  • Modulus of Subgrade reaction - Which one to use

    The modulus of subgrade reaction is an often misunderstood and misused concept for the thickness design of slabs-on-ground. Terzaghi in 1955 (Ref. 1, P. 300) attributed this confusion to the initial work by Hayashi in 1921 (Ref. 2), who stated that the subgrade reaction should be determined by a load test but failed to mention that the tested results depend on the size of the loaded area ...

  • WHAT ARE THE VALUES OF MODULUS OF ELASTICITY

    First of all, (kg/cm^2)*10^5 is not the correct unit for Young’s modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9. Second, if you’re going with GPa, all of these values of Young’s ...
