Splet15. maj 2024 · Young's modulus is a parameter of given material describing relation between force and deformation. The formula is E = σ/ε, where E is Young's modulus, σ = F/A is the tensile stress, or force F over the cross-sectional area A (e.g. string cross-section), and ε = (l - L0)/L0 is relative change of length. The units of E are Pa (pascals); one could … SpletThis paper presents nonlinear finite element simulations of hardness tests which act to provide a mapping of measured Durometer Shore A and D values to the stress-strain behavior of elastomers. In the simulations, the nonlinear stress-strain behavior of the elastomers is first represented using the Gaussian (neo-Hookean) constitutive model.

Splet12. nov. 2024 · The equation for Young's modulus is: E = σ / ε = (F/A) / (ΔL/L 0) = FL 0 / AΔL. Where: E is Young's modulus, usually expressed in Pascal (Pa) σ is the uniaxial stress. ε is the strain. F is the force of compression or extension. A is the cross-sectional surface area or the cross-section perpendicular to the applied force.

SpletIt is denoted as E or Y. Young’s Modulus (also referred to as the Elastic Modulus or Tensile Modulus), is a measure of mechanical properties of linear elastic solids like rods, wires, and such.
