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 ...
On the Propagation of Information and the Use of Localization in Ensemble Kalman Filtering
Publisher: American Meteorological Society
Abstract: Several localized versions of the ensemble Kalman filter have been proposed. Although tests applying such schemes have proven them to be extremely promising, a full basic understanding of the rationale and limitations of ...
Effect of Roots on Water Flow in Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: In recent years, beneficial effects of plants on the remediation of large volumes of slightly contaminated soils have been addressed by various researchers. Water is the main agent moving soluble contaminants in the soil ...
Plant-Enhanced Subsurface Bioremediation of Nonvolatile Hydrocarbons
Publisher: American Society of Civil Engineers
Abstract: In recent years, phytoremediation, i.e., the use of plants to clean up soils contaminated with organics, has become a promising new area of research, particularly for in-situ cleanup of large volumes of slightly contaminated ...
