Arefined FSDT for the static analysis of functionally graded sandwich plates
Best insight from top research papers
A new first shear deformation theory (FSDT) has been proposed for the static analysis of functionally graded sandwich plates. This theory, called S-FSDT, is a four-variable refined plate theory that requires C1-continuity and is based on moving Kriging interpolation . The S-FSDT is computationally efficient, free from shear-locking, and captures the physics of shear-deformation effect present in the conventional FSDT. It can handle both thin and thick plates and is capable of accurately analyzing static bending and free vibration of functionally graded plates . Another study also performs static analysis of functionally graded sandwich plates using the finite strip method based on the refined plate theory (RPT) . Therefore, there are multiple refined FSDT approaches available for the static analysis of functionally graded sandwich plates.

Isogeometric analysis of functionally graded sandwich plate4 answersIsogeometric analysis is used to analyze the behavior of functionally graded sandwich plates. Various theories have been developed to accurately model the bending behavior of these plates. One such theory is the hyperbolic quasi-3D shear deformation plate theory, which reduces the number of unknowns and eliminates the need for shear correction factors. Another theory called the spectral displacement formulation (SDF) uses a unique form of the Chebyshev series to express the displacement field, allowing for accurate bending analysis and satisfying traction-free boundary conditions. Stochastic isogeometric analysis (SIGA) is used to analyze functionally graded plates subjected to random distribution loads, modeling the spatial random variation as a homogeneous Gaussian random field. These theories and methods have been shown to be effective in analyzing the bending behavior, free vibration, and thermo-mechanical properties of functionally graded sandwich plates.
How are Sandwich composite structures modelled?5 answersSandwich composite structures are modelled using various methods. One approach involves designing a sandwich structure with a regular hexagon honeycomb core made of Kevlar® and a carbon fiber face sheet. The design is then modelled and validated using experimental and analytical methods. Another method focuses on improving the flexural response of sandwich structures by adding carbon fiber-reinforced plastic ribs during the manufacturing process. The position of these ribs is investigated using a quasi-static three-point bend test, and a simple FEA approach is used to capture the failure process. Additionally, a strategy for designing large-scale composite sandwich structures involves multi-step optimization techniques, including gradient-based optimization and evolutionary algorithms, to minimize weight and meet mechanical constraints. Finally, a novel design and fabrication strategy proposes the use of architected core structures composed of hollow truncated cone unit cells that dissipate energy and exhibit structural recovery.
How can functionally graded materials be used to improve the mechanical and biological behavior of dental prostheses?5 answersFunctionally graded materials (FGMs) can be used to improve the mechanical and biological behavior of dental prostheses. FGMs are advanced composites that consist of two or more phases graded with spatial position within the structure. The integration of dissimilar materials in FGMs allows for the combination of diverse properties into a single material system. In the case of dental prostheses, FGMs inspired by the structures of human bone, enamel, and dentin-enamel junction (DEJ) can be designed to improve performance compared to traditional prostheses. The gradual variation in composition and microstructure across the dimensions of FGMs enhances their properties, making them suitable for dental applications. By utilizing FGMs in dental prostheses, it is possible to achieve improved mechanical strength, durability, and biocompatibility, leading to enhanced clinical performance and longevity.
