RISDynamic Out-of-Plane Compressive Failure Mechanism of Carbon/Carbon Composite: Strain Rate Effect on the Defect Propagation and Microstructure Failure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Out-of-plane compression experiments with the strain rate from 0.0001/s to 1000/s are performed on a three-dimensional (3D) fine weave-pierced Carbon/Carbon (C/C) composite using a universal testing machine, a high-speed ...
A Dimensionless Quotient for Determining Coupling Strength in Modal Energy Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modal energy analysis (MODENA) is an energy-based method recently proposed to estimate the dynamic response of a coupled structure/acoustic cavity system. The accuracy of MODENA is affected by the coupling strength between ...
Stochastic Dynamic Load Identification on an Uncertain Structure With Correlated System Parameters
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A stochastic dynamic load identification algorithm is proposed for an uncertain dynamic system with correlated random system parameters. The stochastic Green's function is adopted to establish the relationship between the ...
Vibration Characteristics of Aero-Engine With Co-Cavity Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The co-cavity structure replaces the rear bearing cavity and bearing frame of the power turbine shafting. This modification not only reduces the weight of the entire system but also diminishes the axial size of the engine ...
