“…As an illustration, Zenkour [50] used the refined plate theory to examine the bending behavior of a functionally graded material plate under varying bending loads. Ahmed et al [51] and Bouamama et al [52] used it for the dynamic analysis of composite plates and beams respectively. Their findings concluded that the refined plate theory aligns seamlessly with observations and yields notably more accurate outcomes when juxtaposed against the generalized higher-order deformation theory of Reddy [53].…”

In recent years, many countries have been confronted with an extended period of drought, necessitating innovative water supply solutions for both human consumption and agricultural irrigation. In response, wastewater treatment plants (WWTPs) have emerged as pivotal agents in water recycling, catering to agricultural needs and environmental considerations. These plants facilitate the transformation of wastewater into potable or irrigation-ready water. Amidst the array of WWTP designs, the "Continuous-Station" holds a distinctive position, featuring a monolithic steel-structure meticulously crafted from either conventional or stainless-steel. Presently, the prevalent approach involves the application of anti-corrosion paint to protect this monolithic structure from the corrosive effects of aggressive substances present in wastewater. However, an innovative strategy is being exploredthe incorporation of tungsten, an anti-corrosive element, into the stainless-steel alloy. This integration shows promising potential to enhance resilience against the relentless degradation forces within wastewater, simultaneously bolstering the mechanical properties of the steel. This research paper exclusively focuses on analyzing, analytically, the hydrostatic bending performance of WWTP structural components infused with nano-tungsten-particles. The range of incorporation spans from a baseline of 0%, representing the steel without any infusion, to an optimal threshold of 30% relative to the overall volume of the steel matrix. The elastic-properties of the composite steeltungsten alloy are characterized using Mori-Tanaka's homogenization model. The WWPT structural components are simplified as plates and analyzed using an advanced mathematical model based on the refined plate theory. The outcomes underscore a notable enhancement in flexural strength by augmenting the fraction of tungsten nanoparticles within the stainless-steel matrix.

The objective of this work is to analyze the behavior beams functionally graded, simply supported, under different conditions such as bending, buckling, and vibration and this by use shear deformation theories a two-dimensional (2D) and quasi-three-dimensional (quasi-3D). The proposed theories take into account a new field of displacement which includes indeterminate whole terms and contains fewer unknowns, compared to other theories of the literature; by taking account of the effects of the transverse shears and the thickness stretching. In this theory, the distribution of the transverse shear stress is hyperbolic and satisfies the boundary conditions on the upper and lower surfaces of the beam without the need for a shear correction factor. In this type of beam the properties of the materials vary according to a distribution of the volume fraction, the Hamilton principle is used to calculate the equations of motion, and in order to check the accuracy of the theory used comparison is made with the studies existing in the literature.

“…The effects of the initial thermal stress on the natural frequencies were also discussed. Thermal effect on wave propagation of functionally graded plates based on neutral surface position was studied by Boukhari et al [10]. Bourada et al [11] presented a new simple and refined trigonometric higherorder beam theory for bending and vibration analysis of FG beams with including the thickness stretching effect.…”

This paper presents an analytical solution to the free vibration analysis of functionally graded beams by using a refined hyperbolic shear deformation theory in which the stretching effect is included. The modulus of elasticity of beams is assumed to vary according to a power law distribution in terms of the volume fractions of the constituents. Equations of motion are derived from Hamilton's principle and Navier-type analytical solutions for simply supported beams are compared with the existing solutions to verify the validity of the developed theory. Numerical results are obtained to investigate the effects of the power-law index and sideto-thickness ratio on the natural frequencies. It can be concluded that the present theories are not only accurate but also simple in predicting the free vibration responses of FG beams.
