Stress strain curve for compression

WebThe compressive stress–strain curve of concrete is certainly non-linear, so the modulus of elasticity, or modulus of deformation, of concrete varies continuously with the stress or strain. When the equation of the stress–strain curve is determined (Section 2.3), the secant or tangent modulus (E c,s = σ/ε, E c,t = dσ/dε) of concrete can ... WebDec 28, 2024 · The modulus of elasticity equation is used only under conditions of elastic deformation from compression or tension. The modulus of elasticity is simply stress divided by strain: E=\frac {\sigma} {\epsilon} E = ϵσ. with units of pascals (Pa), newtons per square meter (N/m 2) or newtons per square millimeter (N/mm 2 ).
