RISBuckling of Columns With Nonmovable Boundaries
Publisher: American Society of Civil Engineers
Abstract: The global buckling problem of slender tubulaj columns subject to distributed load is studied. The load consists of the column weight, tension/compression exerted at the top of the column, and internal and external variable ...
Selection of Variables for Structural Redesign by Large Admissible Perturbations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Redesign or inverse design is the process of generating a new optimal design which satisfies performance specifications starting from a baseline design with undesirable performance. The LargE ...
Cognate Space Identification for Forced Response Structural Redesign
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large admissible perturbations (LEAP) is a general methodology, which solves redesign problems of complex structures with, among others, forced response amplitude constraints. In previous work, two ...
Routes to Large Amplitude Motions of Mooring Systems Due to Slowly Varying Drift
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of second-order slowly varying wave drift (SVWD) forces on the horizontal plane motions of moored floating vessels has been studied for nearly 30 years. Large amplitude oscillations ...
Static Stress Redesign of Structures by Large Admissible Perturbations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The LargeE Admissible Perturbation (LEAP) methodology is developed further to solve static stress redesign problems. The static stress general perturbation equation, which expresses the unknown ...
Static Stress Redesign of Plates by Large Admissible Perturbations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to develop further the large admissible perturbation (LEAP) methodology to solve the static stress redesign problem for shell elements. The static stress general ...
Revealing Nonlinear Dynamics Phenomena in Mooring Due to Slowly-Varying Drift
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of slowly-varying wave drift forces on the nonlinear dynamics of mooring systems have been studied extensively in the past 30 years. It has been concluded that slowly-varying wave ...
Selective Roughness in the Boundary Layer to Suppress Flow-Induced Motions of Circular Cylinder at 30,000<Re<120,000
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A passive control means to suppress flow-induced motions (FIM) of a rigid circular cylinder in the TrSL3, high-lift, flow regime is formulated and tested experimentally. The developed method ...
Effect of Bottom Boundary on VIV for Energy Harnessing at 8×103<Re<1.5×105
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The concept of extracting energy from ocean/river currents using vortex induced vibration was introduced at the OMAE2006 Conference. The vortex induced vibration aquatic clean energy (VIVACE) ...
Redesign of Submerged Structures by Large Admissible Perturbations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of large admissible perturbations (LEAP) is a general methodology, which solves redesign problems of complex structures without trial and error or repetitive finite element analyses. ...
