...J. Błachut; O. Ifayefunmi This is the first study into elastic-plastic buckling of unstiffened truncated conical shells under simultaneously acting axial compression and an independent external pressure. This is both a numerical and experimental study. Domains of combined stability are obtained...

...Hugo A. Ernst; Richard E. Bravo This work studies the effect of the yield ( Y ) to tensile ( T ) ratio, Y ∕ T , on the structural integrity of line pipes with part through the thickness (PTT) circumferential defects subject to bend loading. A model based on elastic-plastic fracture mechanics...

...S. T. Lie; Z. M. Yang This paper concerns on the development of numerical models for cracked square hollow sections (SHSs) T-, Y-, and K-joints. Based on these numerical models, the plastic collapse loads P c are calculated using nonlinear finite element method and through twice-elastic compliance...

...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...

... on these pipelines, resulting in localized wrinkles well into the plastic range of the pipe material. Eventually, there is a possibility of a fracture occurring at a wrinkled location under continuous deformation. A recent field fracture and a failed laboratory specimen have been observed within a telescopic wrinkle...

...Edward C. Clukey; Charles P. Aubeny, Assistant Professor,; James D. Murff, Visiting Professor, A plastic limit formulation was previously developed for estimating caisson uplift in cohesive soils under general conditions of vertical, horizontal, and inclined loading. The formulation considers...
