Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical concrete column is subjected to an axial force along its length and a lateral pressure from the environment. Calculate the radial and hoop strains, assuming the column radius increases with deformation.
💡 Hint: Remember Poisson’s ratio can link radial and hoop strains.
Question 2
Design a thin-walled pressure vessel and present the critical factors affecting the strain in both radial and circumferential directions as internal pressure increases.
💡 Hint: Look into classical thin-walled approximations for your approach.
