WebYoung's modulus formula. The elastic modulus E can be expressed as the stress divided by the strain as shown in the formula below. Young's modulus [ N / m 2] = stress strain = σ ε = F A Δ L L 0 = F L 0 A Δ L. The units of Young's modulus units are the same as the stress, N/m 2 which is equivalent to Pa (pascal). WebFormally, Young's modulus determines the relationship between stress and strain: E = \frac {\sigma} {\epsilon} E = ϵσ where: E - Young's modulus, \sigma σ - stress, \epsilon ϵ - deformation. Other common names for Young's modulus include: modulus of linear deformation, modulus, longitudinal elasticity, first spring constant. recycling center bostonWeb14 apr. 2024 · The compressive yield strength of the H250 PVC foam and balsa wood doubles when the strain rate is increased from quasi-static rates (10−4 s−1) to rates on the order of 103 s−1. recycling center boerne

"WebThe density of temperate woods varies from about 0.3 to 0.9 gram per cc, but the range worldwide is approximately from 0.2 to 1.2 grams per cc. Differences among species or samples of the same species are due to varying proportions of wood substance and void volume and to content of extractives. " - Modulus of elasticity for balsa wood
