TL;DR: In this article, a unified formulation for the free vibration analysis of open shells subjected to arbitrary boundary conditions and various geometric parameters such as subtended angle, conicity is presented, which can be readily applied to open shells with more complex boundaries such as point supports, nonuniform elastic restraints, partial supports and their combinations.
