r value of aluminum sheet

  • Measuring the plastic strain ratio of sheet metals

    2006-6-13 · The plastic strain ratio, r, is considered a direct measure of sheet metal's drawability and is useful for evaluating materials intended for forming shapes by deep drawing (see lead photo). The r value is the ratio of the true strain in the width direction to the true strain in the thickness direction when a sheet material is pulled in uniaxial ...

  • How to Convert Thermal Conductivity to R Value | Hunker

    Calculate the R-value by taking the reciprocal of the conductivity C to get R = 1/3.93 = 0.254 kelvin-meter^2/watt. You can also calculate the R-value directly as R = L/K = 0.305/1.2 = 0.254 kelvin-meter^2/watt. Notice that the thicker the material is, the higher the R-value is. More of a given material makes a better insulator.
