During the vacuuming, the conservator is subjected to a hydrostatic pressure, which in the case of a thin walls cause buckling. The pressure at which the buckling occurs is largely dependent on the imperfections and damage on the cylinder walls. In this thesis, we first conducted a study of the potential impacts on buckling stability of the conservator. Then we verify these effects numerically with the finite element method in Abaqus 6.131. The results were compared with a variety of analytical and empirical equations from the literature. In the end, a series of pressure tests were carried out on smaller samples of different dimensions and some stiffened. We have found that with a nonlinear numerical analysis we can very well describe the real state. Major deviations occur in the case of stiffened samples.
