courses.washington.eduNormal Stress: Having derived the proportionality relation for strain, ε x, in the x-direction, the variation of stress, σ x, in the x-direction can be found by substituting σ for ε in Eqs. 3.3 or 3.7. In the elastic range and for most materials uniaxial tensile and compressive stress-strain curves are identical. If there are differences in ...

mae.ufl.eduIn the previous section, we introduced the concept of stress, strain and the relationship between stresses and strains. We also discussed failure of materials under uniaxial state of stress. Failure of engineering materials can be broadly classified into ductile and brittle failure. Most metals are ductile and fail due to yielding.

We can then write a constitutive relation between the axial force and the appropriate measure of strain for the beam: N 1 (x 1) = S (x 1) u 0 1 (x 1) (7.10) e3 e2 x i 3 x i+1 3 i = n , E n i, E i

Tensile strength σ max is the tensile stress at maximum force. Tear strength σ B is the tensile stress at the moment of rupture of the specimen.
