... deg showing ( a ) the change in the axial reaction forces versus external pressure for various wall thicknesses and ( b ) failed sample and FE damage state (0 means no damage, 1 means damaged, and 2 means totally damaged) FE results of the textured titanium pipe with N = 6 and α = 30 deg showing...

... at the ultimate external pressure point of the load–deformation–relation curve. The analysis is reliable because the result of the theoretical model is close to the FEA and the test result. (2) The plastic buckling pressure calculated using Eq. (22) can be used to estimate the collapse capacity of the RTP...

...J. Błachut; O. Ifayefunmi This paper studies the static stability of metal cones subjected to combined, simultaneous action of the external pressure and axial compression. Cones are relatively thick; hence, their buckling performance remains within the elastic-plastic range. The literature review...
