SLS 05: Thin cylinder under a uniform axial load

Description

Open handcalculations

$\sigma_1=\sigma_{zz}=\frac{p}{e}=\frac{10kN/m}{0,02m}=5 N/mm^2$

$\Delta R=\delta_x=\delta_z=\frac{p \cdot \nu \cdot R}{E \cdot e}=\frac{10kN/m \cdot 4m \cdot 1m}{210000N/mm^2 \cdot 0,02m}=0,000 714mm$

$\Delta y=\delta_y=\frac{p \cdot L}{E \cdot e}=\frac{10kN/m \cdot 4m}{210000N/mm^2 \cdot 0,02m}=0,009524mm$
