Schematic illustration of the axisymmetric model used for FEA in the current study for two key cases: (Case A) CPA in the absence of a container, where identical temperature boundary conditions are imposed on Ω1, Ω2, and Ω3; and (Case B) CPA contained within a cylindrical vial, where identical temperature boundary conditions are imposed on Ω4 and Ω5, while thermal insulation is assumed on Ω3, consistent with [27]. In both cases zero normal stress is assumed on the outer most surfaces. In Case B, continuity in temperature and displacement are assumed on Ω1 and Ω2. Also illustrated for the purpose of discussion the maximum principle-stress points, σA and σB, for Cases A and B, respectively.
