    A novel EFG meshless-ANN approach for static analysis of FGM plates based on the higher-order theory
    (Taylor and Francis Ltd., 2024) K P, A.; Swaminathan, K.; Indu, N.; H, S.
    An Element Free Galerkin (EFG) meshless formulation and solutions using higher order shear deformation theory with nine degrees of freedom for the static analysis of Functionally Graded Material (FGM) plates are provided. This technique estimates the shape function using Moving Least Squares (MLS) method. The proposed method is validated by comparing the present findings with those in the literature. A novel Artificial Neural Network (ANN) model is developed to forecast the deflection of FGM plates within less computational time. Detailed parametric and convergent studies reveal that the proposed EFG solution and the ANN technique are more efficient than their conventional counterparts. The validation and comparison of the generated results in the present investigation with the other analysis methods revealed that the EFG method and ANN model give more accurate results than the FEM and other meshless methods. The current EFG-ANN model reduces computing time by 99.94% when compared to the EFG approach. Also, the accuracy is enhanced using the EFG approach with HSDT9 for the FGM plate. © 2023 Taylor & Francis Group, LLC.

    An Element-Free Galerkin (EFG) Meshless Solution for Static Analysis of FGM Plates Resting on Elastic Foundation
    (Springer Science and Business Media Deutschland GmbH, 2024) Indu, N.; K P, K.P.; Swaminathan, K.
    An element free Galerkin (EFG) meshless solution method is presented in this paper to illustrate the bending response of FGM plates resting on Winkler–Pasternak elastic foundations. A power law distribution is used to govern the gradation of material properties through the plate thickness. To check the validity of the theory and formulations, the obtained results are compared with the previous results. Comparison studies reveal that the results of the proposed solution method is more accurate and yield faster results than other methods. Parametric studies are performed to show the influences of elastic foundation coefficients and power law index on the deflection of FGM plates. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

    Vibration Analysis of FGM Plates Resting on Elastic Foundation in Thermal Environment Using Element-Free Galerkin (EFG) Meshless Solution
    (Springer Science and Business Media Deutschland GmbH, 2024) K P, K.P.; Indu, N.; Swaminathan, K.
    The present paper deals with the effect of temperature on the vibration characteristics of functionally graded plates resting on two-parameter elastic foundations. The temperature-dependent mechanical properties of the plates are assumed to vary through thickness. The present solutions are derived using an element-free Galerkin (EFG) meshless method. Using the EFG solution method, the numerical results are presented and compared with those available in the literature. Results show that the foundation stiffness, temperature, and other parameters have a significant influence on the vibration response of functionally graded plates resting on elastic foundation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
