Plastic buckling of initially imperfect stiffened cylinders in axial compression
Bifurcation in the plastic range of axially compressed stringer-stiffened cylinders is investigated. The shell under consideration is assumed to have an initial imperfection in the form of a sinusoidal deviation both axially and circumferentially.The constitutive relation employed here is J 2 …

Buckling of composite conical shells under combined axial compression, external pressure, and bending
… composite conical shells subjected to combined axial loading, external pressure, and bending is investigated using energy and finite element methods. The conical shells have single and multiple layers, different cone angle, length, and radius. These parameters are considered to determine optimal …

Effectiveness of high strength repair mortars in structural patch repairs of concrete members under axial compression
… patch repair of concrete elements under axial compression. This was determined with respect to the ability of the repair material to contribute to load sharing in the repaired element under service loads. Three commercially available high strength cement-based repair materials were tested …

Investigation of curved composite panels under high-g loading
… the composite panels. Experimentally, controlled axial compression tests and high-g tests were performed to determine the buckling response of the panels. The buckling response, including critical loads and mode shapes, was obtained for the controlled axial compression tests. The high-g tests …

Mechanical Comparison of a Type II External Skeletal Fixator and Locking Compression Plate in a Fracture Gap Model
… skeletal fixator (ESF) to a 3.5 mm locking compression plate (LCP) in axial compression, mediolateral, and craniocaudal bending in a fracture gap model. The hypothesis was that the Type II ESF would demonstrate comparable stiffness to the LCP. A bone simulant consisting of short fiber …
