The strain state of $\varepsilon_x = 933 \times 10^{-6}$, $\varepsilon_y = -4160 \times 10^{-6}$ and $\gamma_{xy} = 3200 \times 10^{-6}$ exists on a free surface of an orthotropic composite material with the following properties: $E_x = 7500$ ksi, $E_y = 2500$ ksi, $G_{xy} = 1250$ ksi and $\nu_{xy} = 0.3$. Calculate the stresses $\sigma_x$, $\sigma_y$ and $\tau_{xy}$.

Step 1
3 (Poisson's ratio) To calculate the stresses Ox, Oy, and txy, we need to use the equations for stress-strain relationships in an orthotropic material. The stress-strain relationship in the x-direction is given by: σx = Ex * εx The stress-strain relationship in Show more…

Find the residual hoop stress at the outer surface of a thick-walled cylinder made of a material with yield strength of 500 MPa, the inner and outer radii of 100 and 150 mm, respectively. The cylinder was initially subjected to the fully plastic pressure and after that the pressure was released. 84 MPa 117 MPa -67 MPa - 114 MPa 193 MPa 176 MPa

For the two-dimensional stress field shown in Fig. P2.1 it is found that \[ \sigma_{x x}=3000 \text { lbf/ft }^{2} \quad \sigma_{y y}=2000 \text { lbf/ft }^{2} \quad \sigma_{x y}=500 \text { lbf/ft }^{2} \] Find the shear and normal stresses (in $\operatorname{lbf} / \mathrm{ft}^{2}$ ) acting on plane $A A$ cutting through the element at a $30^{\circ}$ angle as shown.
