for quantitatively estimating tensile strength for a given amount of UV exposure energy. This model enables us to easily predict the UV properties of outer layer fabrics of firefighter clothing that retain high mechanical strength by calculating and designing the strength of firefighter clothing with ...

For tensile stresses: "+SN" (or "SN") or "s" (sigma) For compressive stresses: "-SN" or "-s" (minus sigma) The ability of a material to react to compressive stress or pressure is calledcompressibility. For example, metals and liquids are incompressible, but gases and vapors are compr...
