Hi, folks, I'm an aspiring Mechanical Engineer, & as such am very new to the subject of stress, strain, etc. I'm designing an assembly using a hi-performance polymer that has the following characteristics: Tensile Strength, 73°F 10.1 kpsi (10,100 psi) Tensile Modulus (E) 340 kpsi (340,000 psi) Tensile Elongation @ Yield 7.2% Tensile Elongation @ Break 60-120% Flexural Strength, 73°F 13.2 kpsi Flexural Modulus, 73°F 350 kpsi Tensile Impact Strength 190 ft-lb/in^2 Izod Impact, Notched, 73°F 13 ft-lb/in^2 In order to model my FEA under Cosmo/Solidworks, I need to supply the following information: (Most, I believe, I have derived.) Elastic(Tensile?) Modulus E=340,000 lb/in^2 Poissons Ratio ν=(E/(2*μ))-1 Shear Modulus μ=?? Thermal Expansion Cooeficient 31 ppm/°F = 3.1e-006 Density .0466 lbs/in^3 Thermal Conductivity ---?? Specific Heat 0.27 BTU/lb-degF Tensile Strength 10100 lb/in^2 Yield Strength (Flexural?) ?? I'm particularly confused about the Yield Strength. Can it be determined with available information? What about the Shear Modulus? I'm also not sure it's appropriate to enter the "Tensile Modulus" into the field for "Elastic Modulus" as I know the latter is more general than the former. Thanks for any help!
