The Young’s Modulus values of different material are given below: Steel – 200 Glass – 65 Wood – 13 Plastic (Polystyrene) – 3 Young’s Modulus Factors By understanding themodulus of elasticity of steel, we can claim that steel is more rigid in nature than wood or polystyrene, as its...
Since elongation is dimensionless, modulus has the units of stress. The relevant ASTM test is D 638. In contrast to structural metals such as mild steel, the stress-strain graphs for many plastics exhibit some curvature, even at very low strains. Since there is then no significant linear ...
The modulus of elasticity of stainless steel orthodontic wires was found to be 20% below the normally assumed range of 19.3 to 20.0 x 10(4) MPa (28.0 to 29.0 x 10(6) psi). Use of the latter value can result in significant computational errors in orthodontic applicance mechanics. The ...

Results for the solid wires approximated their tensile values, but the differences were statistically significant for the stainless steel, chromium-cobalt-nickel, and nickel-titanium alloys. The flexure moduli of the multi-stranded wires ranged from 0.89 to 5.11 X 10(6) psi, and were dependent ...
