RISA Jacobi–Ritz Approach for Aeroelastic Analysis of Swept Distributed Propulsion Aircraft Wing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents a Jacobi–Ritz approach for conducting flutter and divergence analysis of a complex distributed propulsion aircraft wing similar to that of NASA X-57. The general orthogonal Jacobi polynomials are used ...
Displacement Error Propagation From Embedded Markers to Brain Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Head injury model validation has evolved from against pressure to relative brain–skull displacement, and more recently, against marker-based strain. However, there are concerns on strain data quality. In this study, we ...
Investigation of Numerical Evaluation Improvement for Three-Dimensional Infinite Cylindrical Heat Conduction Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To estimate the thermal properties from transient data, a model is needed to produce numerical values with sufficient precision. Iterative regression or other estimation procedures must be applied to evaluate the model ...
Surface Coating Modification of Cathode Material for Long-Term Stable All-Solid-State Batteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The decomposition of solid electrolytes at the surface of the cathode has become one of the critical bottlenecks in the further widespread of all-solid-state batteries. To this end, we applied a fluidized bed coating method ...
A Shape and Size-Scaled Deep Learning Brain Injury Model for Near Real-Time Dynamic Impact Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Efficient deep learning brain injury models enable large-scale, strain-based investigations of traumatic brain injury (TBI). Here, we extend a previous model based on a generic 50th percentile adult male brain ...
Convolutional Neural Network and Image Processing-Based Approach for Homogenization of Lattice Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The homogenization approach is widely used in lattice structure design to simplify modeling of complex geometries by representing them as simple solid elements in finite element analysis (FEA). Homogenized material ...
Aerodynamic Design and Analysis of a Multistage Vaneless Counter Rotating Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multistage vaneless counterrotating turbine (MVCRT) eliminates vanes between rotors, which reduces the weight and size of the turbine and avoids viscous losses associated with vanes pronouncedly. An aircraft engine ...
Enhanced Diapycnal Mixing in the South China Sea
Publisher: American Meteorological Society
Abstract: Profiles of current velocity, temperature, and salinity were obtained in the Internal Wave and Mixing Experiment in the South China Sea (SCS), the Luzon Strait, and the North Pacific. The observations are examined for ...
Study on Laser-Induced Oxidation of Ti6Al4V Alloy Under Two Different Reactive Atmospheres
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The oxidation behavior of Ti6Al4V titanium alloy under laser irradiation in atmospheric and oxygen-assisted conditions was studied. A nanosecond-pulsed Yb: glass fiber laser was used. The thickness of oxide layer, ...
Analysis of Instantaneous Vibrational Energy Flow for an Aero-Engine Dual-Rotor–Support–Casing Coupling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aero-engine casing is a key component for carrying loads. With the purpose of improving the thrust-weight ratio of the aero-engine, the casing is required to be designed to be as thin as possible. Therefore, the vibration ...
