The classical well-known morphological stability criterion, according to Plateau-Rayleigh (PR) theory, was systematically corrected, considering both linear/non-linear stability analysis as well as energetic concept. Analyzing the initial curvature distribution, we propose an alternative stability which dramatically improves existing theories. We find a metastable region for the critical configuration from the energetic concept and further identify the stability criterion by examining the morphological changing mechanisms: surface diffusion and mean curvature flow. The thermodynamically consistent phase-field models capture these two mechanisms and strongly confirm the present criterion.
