RISUncoupled Wave Systems and Dispersion in an Infinite Solid Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, it is shown that there exist uncoupled wave systems for general non-axisymmetric wave propagation in an infinite isotropic cylinder. Two cylindrical surface conditions corresponding ...
Modified Mixed Variational Principle and the State-Vector Equation for Elastic Bodies and Shells of Revolution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modified mixed variational principle is established for a class of problems with one spatial variable as the independent variable. The specific applications are on the three-dimensional deformation ...
Static Axisymmetric End Problems in Semi-infinite and Finite Solid Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Our earlier technique for a semi-infinite strip (Kim and Steele, 1990) is extended to study general end problems and corner singularities for semi-infinite and finite solid cylinders with free ...
Analysis of Piezoelectric Energy Harvesters of a Moderate Aspect Ratio With a Distributed Tip Mass
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various mathematical beam models have been proposed for the efficient analysis of a piezoelectric energy harvester (PEH) and carrying out parameter study but there appears no beam model suitable ...
End Effects and Time-Harmonic Longitudinal Wave Propagation in a Semi-Infinite Solid Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axisymmetric end problems of longitudinal wave propagation are studied in a semi-infinite isotropic solid circular cylinder which is free of traction on its cylindrical surface. An accurate and ...
Modifications of Series Expansions for General End Conditions and Corner Singularities on the Semi-Infinite Strip
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified series expansions are used to study semi-infinite isotropic elastic strip problems for general end conditions and corner singularities. The solutions of strips with mixed lateral edges ...
Effects of Lateral Surface Conditions in Time-Harmonic Nonsymmetric Wave Propagation in a Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work is a part of the effort toward the development of an efficient method of solution to handle general nonsymmetric time-harmonic end conditions in a cylinder with a traction-free ...
Fully Coupled 10-Degree-of-Freedom Beam Theory for Piecewise Straight Thin-Walled Beams with General Quadrilateral Cross Sections
Publisher: American Society of Civil Engineers
Abstract: A fully coupled 10-degree-of-freedom (DOF) beam theory is developed for the analysis of thin-walled closed piecewise straight beams of general quadrilateral cross sections. The developed beam theory can predict the structural ...
Exact Matching Condition at a Joint of Thin-Walled Box Beams Under Out-of-Plane Bending and Torsion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To take into account the flexibility resulting from sectional deformations of a thin-walled box beam, higher-order beam theories considering warping and distortional degrees of freedom (DOF) in ...
Design Optimization of Compliant Mechanisms Consisting of Standardized Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We developed a design method to configure optimal compliant mechanisms consisting of standardized elements such as semirigid beams, hubs, and joints. In the proposed design approach, mechanism ...
