This paper presents an element-free Galerkin (EFG) method for the forced vibration analysis
of stiffened plates based on the first-order shear deformation theory (FSDT), and the …

In this paper, a strain gradient continuum model for a metamaterial with a periodic lattice
substructure is considered. A second gradient constitutive law is postulated at the …

To investigate the mechanical deformation characteristics of the 'Segment-SCC-Steel
Tube'combined bearing lining structure under internal and external pressure, the loading …

过约束状态下的结构内部转角不连续, 会导致结构变形场难以准确重构. 本文以飞行器进气道
典型三维壁板结构为对象, 开展超静定状态下结构变形场重构方法研究. 将子区域划分与逆有限 …

The flow pattern, mass flow rate, and stability of discharge rate of conical hoppers and
hyperbolic hoppers with different diameters and initial inclination angles were studied by the …

Abstract Wave 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 …

Free and forced vibrations of Z-reinforced sandwich plates stiffened by steel ribs are
researched by experimental and mixed analytical–numerical techniques. A test sample of …

Free and forced vibrations of a periodically stiffened plate made of exponential functionally
graded material (FGM) are investigated, accounting for the in-plane deformations. Based on …

In this present investigation, an eight-nodded isoparametric finite element method is used to
model the geometry of the stiffened plate based on first-order shear deformation theory …

As a thin-walled structure, it is impractical or uneconomical to scale the thickness of stiffened
plate with the same scale factor as the length, which leads to geometric distortion and the …
