Elementary morphing shells
Multistable shells are not yet completely understood. Even under the widespread Uniform Curvature (UC) assumption, the limits of this behaviour have not been established and the influence of individual material and geometric parameters has not been described conclusively; this research explores …

Cord-Reinforced Cylindrical Shells
… analysis of the bending of circular cylindrical shells by Flugge, an equilibrium approach. These equations are solved analytically in closed form for axisymmetric loading. The resulting load--deformation relations are strongly dependent upon the properties of the constituents, including the …

Atomic processes in nova shells
… unusual spectra of the spatially-resolved nova shells of DQ Her, T Aur and CP Pup are reviewed. Because calculations for these conditions have not been made, recombination models of HI, HeI and CNO from a neutral to a doubly ionized state were constructed. The models are described and the …

Stability of elastic grid shells
… pre-stress of an initial structure. Elastic grid shells seem particularly promising as shelters, lightweight roofs, or kinetic structures. Although fundamental to the behavior of the strucure, the influence of the pre-stress on the stability of elastic grid shells has yet to be studied. …

Injection molding of shotgun shells
… of producing injection molded shotgun shells was explored. Also, the molding cycle and the effect of molding conditions on the mechanical properties of molded parts were investigated. The polymer obtained from a commercial brand of shotgun shells was analyzed using infrared spectroscopy …

Analysis of Pressurized Arch-Shells
… is utilized to determine the behavior of arch-shells under various types of loading. The types of loading include a uniformly distributed vertical load representing snow, a wind load, and a horizontal side load distributed along the arc length. Deflections, stress resultants, and moments at …

Stability analysis of edge corrugated shells
The practical construction of reinforced concrete shells highlights two points, both of theoretical and practical interest: 1. in the neighbourhood of the edge, the membrane state is not representative of the actual stress and strain, and the effect of bending moments must be taken into account; 2. …

Torsion of Elliptical Composite Cylindrical Shells
The response of elliptical composite cylindrical shells under torsion is studied. The torsional condition is developed by rotating one end of the cylinder relative to the other. Prebuckling, buckling, and postbuckling responses are examined, and material failure is considered. Four elliptical cross …

Elastoplastic buckling of doubly curved unstiffened shells
… values for the buckling pressure of thin shells has become very Important in recent years. The increased necessity and usage of lighter weight components in missile propulsion systems has required more precise calculations to avoid stability problems and to increase economic feasibility. …

Concentrated Gauss Curvature in Shape-Programmed Shells
… paradigm of `metric mechanics', in which active shells respond to stimuli by undergoing large spontaneous deformations. Our focus will be on novel ways to program Gauss curvature, motivated by its deep mechanical consequences - principally it imparts strength, since Gauss-curved shells cannot be …
