    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.

    Microstructure, mechanical and wear properties of SiC and Mo reinforced NiCr microwave cladding
    (Taylor and Francis Ltd., 2024) H, S.; Ravi Prakash, R.; Prasad, C.D.; Ramesh, M.R.; Phanibhushana, P.; Vasudev, H.; Kumar, S.
    The NiCrMoSiC composite cladding on Titan-31 base alloy was produced using a hybrid microwave heating process. The produced claddings were examined for microstructural, phase analysis, microhardness, and surface roughness using suitable techniques. The linear reciprocator ball on plate wear test was conducted using a static alumina indenter on microwave cladding. Studies have been done on track specifications for friction and wear. It is feasible to fabricate a dense microstructure with uniform distribution of hard phases, absence of pores and fractures, and strong metallurgical bonds. Typically, cladding is two times as durable as the underlying metal. The cladding has a lower coefficient of friction than the substrate as a result of enhanced hardness and improved internal lubricity brought on by the production of hard carbide phases. © 2023 Informa UK Limited, trading as Taylor & Francis Group.
