RISA Green's Function for the Domain Bounded by Nonconcentric Spheres
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main result is the analytical derivation of Green's function for the domain bounded by nonconcentric spheres in terms of bispherical coordinates. Both surfaces, inner and outer boundaries, are specified by the Dirichlet ...
True and Spurious Eigensolutions of an Elliptical Membrane by Using the Nondimensional Dynamic Influence Function Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we employ the nondimensional dynamic influence function (NDIF) method to solve the free vibration problem of an elliptical membrane. It is found that the spurious eigensolutions appear in the Dirichlet problem ...
Steady State Heat Conduction in Exchanger Tubes by Using the Meshfree Boundary Integral Equation Method: Conduction Shape Factor and Degenerate Scale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regarding the steady-state heat conduction problem in exchanger tubes, the meshfree boundary integral equation method is employed to determine the conduction shape factor in this paper. Different from the conventional ...
Thermal Stress Analysis of Free-Free Trusses under Temperature Change Using a Self-Regularized Approach
Publisher: American Society of Civil Engineers
Abstract: AbstractIn this study, a self-regularized approach was employed to determine the thermal stress
in a free-free truss, which results in a singular stiffness matrix. Physically, the
stiffness and flexibility matrices of ...
Animations and Properties of Three SDOF Damping Systems
Publisher: American Society of Civil Engineers
Abstract: Three models—the viscous damping model, the new hysteretic damping model, and the Coulomb damping model—are studied in this paper. For the viscous damping and the Coulomb damping models, the free vibration problem is ...
