Response of Surface Cracks in Tubular Members During Global Buckling and Instability
Abstract Beam-columns in compression are subject to potential buckling. If the axial load is combined with a global bending moment, member instability may occur. One situation where this can occur is for pipelines on the seabed, where thermal...
