【2021-Aerospace Science and Technology】An efficient wave based method for the mid-frequency transv...
AbstractWave Based Method (WBM) is an efficient method to analyze mid-frequency dynamic problems. This work extended the WBM to the transverse vibration analysis of a thermal beam with limited uncertain information. Novel wave functions and particular solution function for the thermal beam with dete...
【2021-ASME-Journal of Computational and Nonlinear Dynamics】Sensitivity Analysis of Nonlinear Trans...
AbstractSensitivity 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 response using the real-imaginary perturbations (RIP) in the complex doma...
【2021-AIAA-Journal of Aircraft】Distributed Dynamic Load Identification on Irregular Planar Structu...
AbstractSpatially distributed load on aircraft structures is difficult to obtain due to the limitation of measurement technology, the complexity of load and the external environment of the aircraft during flight, etc. A load identification method based on a subregion interpolation technique is propo...

HighlightsA modified perturbation stochastic finite element model(MPSFEM) is proposed.A stochastic load identification(SLI) algorithm based on MPSFEM is developed.A standard SLI framework for complex uncertain structures is developed.Graphical abstractAbstract Estimating the statistics of stoc...
【2020-Ceramics International】Novel statistical analysis method for determining shear strength of C...
Abstract The discreteness of strength seriously restricts the wider use of Carbon/Carbon (C/C) composites. The strength of C/C composites is studied by using statistical analysis methods. Here, a novel statistical analysis method named B-distribution is proposed to examine the shear strength o...
