Finite Element Modeling and Analysis for Creep Buckling of a Cylindrical Shell Subjected External Lateral Pressure with Local Wall Thinning

open access: yesApplied Sciences
The corrosion, erosion, or worn defects on cylindrical shells often lead to localized wall thinning. The influence of the local wall-thinning defects on the creep buckling behavior of the cylindrical shells serving in high-temperature environments with ...

Parametric study of the structural and in-plane buckling analysis of ogee arches

open access: yesHBRC Journal, 2014
As part of a pilot project an ogee arch is being studied as a self-supporting skin skylight for the Housing and Building National Research Center’s (HBRC) patio. The ogee arch consists of a pair of two tangential circular arcs making an arch shape.
