The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain. For small values of these changes, is the amount of transversal elongation divided …

Webrefers to the response of PE, over time, to a constant static load. When HDPE is sub-jected to a constant static load, it deforms immediately to a strain predicted by the stress–strain modulus determined from the tensile stress–strain curve. The material continues to deform indefinitely at an ever decreasing rate. If the load is high enough, WebThe following product material Poisson ratios should be used: Material Poisson Ratio … WebPoisson's Ratio 0.37 - 0.44 (oriented) Young's Modulus of Elasticity (109 N.m2) 2 - 2.7 Tensile Modulus (GPa) 2 - 4 Tensile Strength (MPa) 80, for biax film 190 - 260 Physical Properties Density (g.cm-3) 1.3 - 1.4 Flammability Self Extinguishing Limiting Oxygen Index (%) 21 Refractive Index 1.58 - 1.64 Resistance to Ultra-Violet Good how to do a statement
