We present mathematical dependences describing the research results for metal half-sperical shells subjected to static loading by external pressure. We studied the behavior and conditions of static buckling of empty, styrofoam- filled and geometrically imperfect shells. Regression equations in the form of incomplete cubic polinomials are derived. In planes of governing parameters we plot isolines, analysis of which makes it possible to draw qualitative and quantitative conclusions on the externally pressurized shell behavior.
