This lecture outlines the deformation mechanisms in a hollow cylinder, specifically focusing on extension, torsion, and inflation. It discusses the mathematical modeling of combined effects due to axial force, torque, and internal pressure, employing cylindrical coordinates. Key physical assumptions and conditions that affect the displacement and stress components are detailed, providing foundational insights for solving complex mechanical problems related to hollow cylinders.
Extension in a hollow cylinder occurs due to applied axial force, leading to stretching.
Torsion arises from rotating the ends of a cylinder in opposite directions, causing twist.
Inflation occurs when internal pressure alters the radius of a hollow cylinder.
The stretching of a cylindrical object when normal traction is applied to its ends.
A twisting deformation in a cylindrical object due to torque applied at its ends.
The increase in radius of a hollow cylinder due to internal pressure applied from within.
A condition wherein the displacements and stresses do not depend on the angular coordinate, simplifying the analysis.
The mathematical relationship that connects stress components to strain components in materials.
