    Abstract

    Compressive buckling of hollow cylinders due to internal pressure is a little-known phenomenon that can affect pressure testing of plastic pipe. High strength pipe materials with large dimension ratios particularly exhibit the phenomenon, but it can also occur in pipe with low dimension ratios (relatively thick walls) when the material is highly elastic or plastic at the test conditions. To successfully test such materials may require special constraints on test geometry and end closures. Specific examples of the phenomenon observed in the laboratory are discussed along with an analytical treatment from the literature.
