Determine the influence factor of geometrical parameters on the dynamic characteristics of the micro crab-shaped beam Open
Microelectromechanical devices are being used much more in science and technology to reduce energy consumption and increase accuracy. The design of mechanical structures in these devices requires reducing the cost of testing and prototype …
APPLICATION OF THE ARIMA MODEL TO FORECASTING THE CONSTRUCTION MATERIAL PRICES: A CASE STUDY IN VIETNAM Open
The ARIMA (Auto Regressive Integrated Moving Average) model has been widely used in forecasting time series data across various fields. Introduced by Box and Jenkins in 1974, this model offers flexibility, accuracy, and reliable confidence…
Bending and buckling responses of organic nanoplates considering the size effect Open
As humanity progresses, fossil fuel reserves are being increasingly exhausted, leading to increased focus on sustainable energy alternatives. Scientists are now researching solar panels that can efficiently convert solar energy into electr…
Finite element modelling for free vibration response of cracked stiffened FGM plates Open
This paper presents the new numerical results of vibration response analysis of cracked FGM plate based on phase-field theory and finite element method. Effects of geometrical and material properties on the vibration behaviors of the plate…

Finite Element Modelling of a Composite Shell with Shear Connectors Open
A three-layer composite shell with shear connectors is made of three shell layers with one another connected by stubs at the contact surfaces. These layers can have similar or different geometrical and physical properties with the assumpti…
A Finite Element Model for Dynamic Analysis of Triple-Layer Composite Plates with Layers Connected by Shear Connectors Subjected to Moving Load Open
Triple-layered composite plates are created by joining three composite layers using shear connectors. These layers, which are assumed to be always in contact and able to move relatively to each other during deformation, could be the same o…
