Publisher: The American Society of Mechanical Engineers (ASME)
Stress Analysis of Pressure Vessels With Uniformly Spaced Lugs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stresses and displacements in circular cylindrical shells having square and rectangular lugs have been studied in this paper. The analysis presented here is based on finite element technique ...
Dynamic Response of Cross-Ply Laminated Shell Panels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fiber-reinforced composites are being widely used in the aircraft and aerospace industry, as well as in other field such as automobile, electronics, etc. In this work, a method based on the ...
Effect of Internal Pressure on Flexibility Factors in Pipe Elbows With End Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element method has been used in the present work to study the stress distribution in an elbow with end constraints subjected to in-plane moment and pressure. Elbows of short radius ...
Asymmetric Modes and Associated Eigenvalues for Spherical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Free asymmetric vibration of spherical shells with clamped and hinged boundary conditions are analyzed using the finite element method. Element stiffness and consistent mass matrices are derived ...
Some Results on Axisymmetric Vibration of Spherical Shells of Variable Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural frequencies and mode shapes are presented for the free axisymmetric vibration of spherical shells with linearly varying thickness along the meridian. Clamped and hinged edges corresponding ...
Identification of Environmental Categories for Markovian Deterioration Models of Bridge Decks
Publisher: American Society of Civil Engineers
Abstract: In general, state-of-the-art bridge management systems have adopted Markov-chain models to predict the future condition of bridge elements and networks in different environments when various maintenance actions are ...
Dynamic Response of Sandwich Shells of Revolution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Development of an annular finite element, for the linear elastic analysis of sandwich shells, is reported here. The derivation of stiffness and mass matrices is based on improved shell theory ...
Segmental and Conventional Precast Prestressed Concrete I-Bridge Girders
Publisher: American Society of Civil Engineers
Abstract: Conventional precast I-girder bridge systems are widely used in North America for short and medium spans, up to 45 m. Spliced standard precast I-girder segments made continuous by longitudinal posttensioning have been used ...
