Abstract: Mechanical properties of the polymer composites are rate-dependent. The representative volume element (RVE) of unidirectional composites considering the rate-dependent effect of polymers is established with the Improved ...

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 ...

Abstract: Sensitivity analysis of transient response plays a crucial role in structural dynamics optimization. In this paper, the sensitivity analysis method for calculating the first-order derivatives of the nonlinear transient ...

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 ...

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 ...

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 ...
