Question

A strain gauge system is mounted at a point on a structural member that is subjected to multiaxial stress. The following readings are obtained: ex = 3.079 x 10^-3, Ey = -3.471 x 10^-3, Ez = 1.207 x 10^3, Yxy = 3.743 x 10^-3. Determine the stress components if the member is made of an isotropic material with linear elastic behavior and the following elastic properties: Young's modulus E = 70 GPa and shear modulus G = 26.7 GPa.

Step 1

We have the strain components: $$\epsilon_x = 3.079 \times 10^{-3}$$ $$\epsilon_y = -3.471 \times 10^{-3}$$ $$\epsilon_z = 1.207 \times 10^{-3}$$ $$\gamma_{xy} = 3.743 \times 10^{-3}$$ Show more…
