Vibration Analysis FGM Plate: A Hybrid Analytical and Machine Learning Approach

Authors:

Abstract

This study investigates the free vibration characteristics of functionally graded material (FGM) plates through both analytical solutions and machine learning (ML) approaches. Starting with deriving equilibrium equations for FGM plates via Hamilton's principle, we accurately determine their natural frequencies under various conditions. Subsequently, we employ an Artificial Neural Network (ANN) model, trained on an extensive dataset from previous research, to predict these vibrational frequencies [1]. The ANN's predictions are meticulously compared with our analytical findings and corroborated against existing studies, showcasing the model's high level of precision and computational efficiency. Notably, the research reveals that the ANN model can significantly streamline the analysis process, handling complex patterns in data that traditional methods find challenging. This blend of analytical rigor and ML innovation offers a novel pathway for enhancing the structural analysis and design of FGM plates, potentially revolutionizing material science and engineering practices. The precision with which the ANN model predicts the natural frequencies across a diverse range of FGM plates underscores the power of data-driven approaches in engineering analysis. The integration of ML not only augments the accuracy of traditional methods but also introduces a level of adaptability and scalability previously unattainable. Our findings suggest that the convergence of computational mechanics and artificial intelligence holds immense promise for the future of material design and optimization, offering a more holistic understanding of the dynamic properties of FGM plates. Furthermore, this study sets a precedent for the application of ML in complex engineering problems, encouraging further exploration into hybrid methodologies that can bridge the gap between theoretical analysis and practical engineering solutions [2]. Through this innovative approach, we aim to contribute to the advancement of FGM technology, paving the way for the development of more resilient and efficient structural components.

Presented herein is the free vibration analysis of functionally graded beams (FGMs) via higher-order shear deformation theory and an artificial neural network method (ANN). The transverse displacement (w) is expressed as bending (wb) and shear (ws) components to define the deformation of the beam. The higher-order variation of the transverse shear strains is accounted for through the thickness direction of the FGM beam, and satisfies boundary conditions. The governing equations are derived with the help of Hamilton’s principle. Non-dimensional frequencies are obtained using Navier’s solution. To validate and enrich the proposed research, an artificial neural network method (ANN) was developed in order to predict the dimensionless frequencies. Material properties and previous studies were used to generate the ANN dataset. The obtained frequency values from the analytical solution and ANN method were compared and discussed with respect to the mean error. In conclusion, the solutions were demonstrated for various deformation theories, and all of the results were thereupon tabularized and visualized using 2D and 3D plots.

PurposeThe aim of this paper is to quantify the stochastic effect for functionally graded (FG) plate in conjunction to free vibration and impact loading.Method The variabilities in geometric and materials properties are considered. A support vector machine (SVM) is employed to construct the surrogate model. The constructed model portrays significant accuracy along with computational cost effectiveness. The output parameters are peak contact force, peak impactor displacement, and peak plate displacement for impact analysis, and the first three natural frequencies are considered for free vibration analysis.Results and Conclusions The results are portrayed in the form of probability density function (PDF), scatter, and the error plots. Sensitivity analysis is performed to know the effect of each input parameter in the present stochastic model. The integration of scale effect i.e., from micro to macro homogenization of the isotropic functionally graded plate is performed for young’s modulus, shear modulus, and Poisson’s ratio. This analysis is important for quality control at the time of design and manufacturing of such components.
