RISEstimation of Forcing Function for a Geometrically Mistuned Bladed Rotor Via Modified Modal Domain Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified modal domain analysis (MMDA) is a method to generate an accurate reducedorder model (ROM) of a bladed disk with geometric mistuning. An algorithm based on the MMDA ROM and a state observer is developed to estimate ...
Fly Ash Concrete Specimens Admixed with Nanoparticles and Their Interaction with Seawater
Publisher: American Society of Civil Engineers
Abstract: This study is on fly ash (FA) concrete admixed with TiO2 nanoparticles (FAT), CaCO3 nanoparticles (FAC), and an equal ratio of TiO2 and CaCO3 nanoparticles (FATC) were exposed to seawater for 365 days in order to find the ...
Measurement of Multiscale Thermal Transport Phenomena in Li-Ion Cells: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance, safety, and reliability of electrochemical energy storage and conversion systems based on Li-ion cells depend critically on the nature of heat transfer in Li-ion cells, which occurs over multiple length ...
Torsional Wave Propagation in a Substratum over a Dry Sandy Gibson Half-Space
Publisher: American Society of Civil Engineers
Abstract: The propagation of torsional surface waves in a transversely isotropic substratum lying over a dry sandy gibson half-space in the presence of initial stress (compressive and tensile) and gravity have been studied analytically ...
Effect of Corrugation and Imperfect Boundary on the Propagation of Rayleigh Waves in Sandy Half-Space beneath an Anisotropic Layer
Publisher: American Society of Civil Engineers
Abstract: An analysis of the propagation behavior of Rayleigh wave has been conducted in an anisotropic layer, such as reservoir rocks overlying a sandy medium. The layer and lower half-space interface have been considered imperfect, ...
Dispersive Constraints of Antiplane Shear Waves in a Strain-Gradient LoH Model under an Inflexible Boundary Plane and Initial Pressure
Publisher: American Society of Civil Engineers
Abstract: This research work depicts the dispersive limitation of shear (SH) waves in an initially stressed strain-gradient layer over halfspace (LoH) model with an inflexible upper boundary plane. The gradient elasticity theory ...

Modified Modal Domain Analysis of a Bladed Rotor Using Coordinate Measurement Machine Data on Geometric Mistuning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified modal domain analysis (MMDA), a reduced order modeling technique, is applied to a geometrically mistuned integrally bladed rotor to obtain its natural frequencies, mode shapes, and forced response. The geometric ...
Modeling and Stress Analysis of Ballasted Tracks: Integrated Finite-Element and Discrete Support Techniques
Publisher: American Society of Civil Engineers
Abstract: Abstract This paper presents a computational study focused on establishing the criticality
of rail cant in redistributing stresses within ballast tracks. A three-dimensional
finite-element model (FEM) was developed and ...
A Case-Based Study of Corrugated Boundaries in a Trilayered Structure and Their Influence on LT Waves
Publisher: American Society of Civil Engineers
Abstract: Abstract The study delves into an analytical examination of the constraints and propagation
of Love-type transverse waves (LT waves) within a three-layered sandwich structure.
To tailor the structure for sensor and actuator ...
