A new identification method of impact load is proposed based on the transient statistical
energy analysis theory in the paper. Firstly, the location and input energy of impact load are …

This paper is concerned with the prediction of vibrations at high frequencies in built-up
structures. In the high-frequency range, the dynamical behaviour of structures is driven by …

A new approach to the calculation of vibrations of weakly damped elastic structures in the
medium-frequency range, called the variational theory of complex rays (VTCR), is being …

This study uses a spectral method to study wave scattering by the local defect in the
structural waveguide. The force response is decomposed into some subproblems by …

This paper addresses the problem of vibration sources identification in coupled thin plates at
high frequency range. An energy-based method called Simplified Energy Method (MES) is …

Launch Vehicles are subject, at lift-off and during flight ascent, to acoustic and aeroacoustic
loads, which are random in nature. Because electronic units are very sensitive to mid and …

This paper deals with the behavior of acoustic cavities in the mid-high frequency range. The
method proposed here is based on an energy flow method named Simplified Energy …

As research works of the transient statistical energy analysis (TSEA) and transient local
energy approach (TLEA) mostly focus on simple structures, TSEA and TLEA are adopted to …

Energy finite element analysis (EFEA) has been successfully applied to steady-state
response prediction over the past three decades. Compared with other energy-based …

The statistical energy analysis (SEA) is applied to predict the transient energy response of
structures with time-varying parameters for the first time. With the energy governing …
