Ductility can be quantified by the fracture strain, which is the engineering strain at which a test specimen fractures during a uniaxial tensile test. Another commonly used measure is the reduction of area at fracture.The ductility of steel varies depending on the alloying constituents.his tensile test of a nodular cast iron demonstrates low ductility. In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.
Spacer fabric is a specialized three-dimensional textile that uniquely facilitates air flow, breathability and lightweight shape support.pacer fabric is a specialized three-dimensional textile that uniquely facilitates air flow, breathability and lightweight shape support.
At MSR, we carefully consider how thread count, fabric type and denier (fiber thickness) will affect the overall tent performance, and we make our decisions based not only on how the tent will be used (e.g. thru-hiking, weekend backpacking, basecamping), but also on where the fabrics are used in the different parts of the tent.
