In this investigation, the Mechanical Behavior of the composite Single-Stringer structure was subjected to numerical analysis in order to better understand its properties. As the primary material for the modeling process, the carbon-epoxy IM7/8552 with quasi-isotropic Layups has been utilized. The outcomes of the numerical analysis that were carried out on the structure while it was in its static state have been put into the structural tool that was developed by the ANSYS programme. The fundamental boundary conditions have been defined on the basis of the information that was received from the testing. Static forces with a combined magnitude of 13.7 kN are being applied to the composite Single-Stringer structure. Shear stresses, direction deformation, von mises stresses, and total deformation have all been shown to have an effect on a material's mechanical behaviour, and this effect has been demonstrated. The calculations indicate that there is a maximum amount of bending that can take place as a direct result of the load that is being applied, and that amount is equal to 0.0147. The maximum amount of bending that can take place as a direct result of the load that is being applied is equal to 0.0147. As a consequence of the application of 13.7 kN of pressure, the von Mises stress, which is also frequently referred to as comparable stresses, has reached 51.9 MPa. Shear stresses have been estimated in three distinct plans, and it was discovered that the shear stress that was applied to the XY plane achieved a maximum of 15 MPa, but the shear stress that was applied to the XZ plane reached a maximum of 9.8 MPa. This was found. Both aeroplanes were put through precisely the same amount of tension at the exact same time. At this time, the shear stress on the plane YZ has reached a level of 1.5 MPa.

“…Xavior et al [11] conducted a more in-depth experimental study of the failure of split FG beams made of porous polymer materials utilizing flexural, tensile, and compressive experimental procedures. Ali Dogan [12] used an analytical model to investigate the quasi-static and dynamic behavior of FGM viscoelastic plates under dynamic loads. The acquired findings were compared to the FEM approach results.…”

This paper studies the mechanical behavior of functionally graded material viscoelastic (FGVE) products employed in automotive, chemical industry, and biomedical appliances. Various experimental models describe and simulate nanobeams with viscoelastic layers subjected to tensile loading, 3-point bending, tear, and impact. All specimens were prepared using the 3D printing method. Tensile, hardness, tear, impact, and bending specimens reinforced with different volume fractions (1-5)% of Al2O3, TiO2, and a hybrid of the nanomaterials Al2O3 /TiO2 were arranged via a mixing process with an extruder and then fabricated by a 3D printing machine. The experimental results of maximum bending load, midspan deflection, impact, and tear resistance were validated by finite element methods (FEM) with the assistance of commercial software (Ansys Workbench 2021 R1). Furthermore, the influence of various parameters on the mechanical performance of reinforced samples has been thoroughly investigated, for example, volume fraction index, nanoparticles content, and FG properties. Based on the findings, the most successful results were obtained by adding 1.5 % Al2O3 and 3% TiO2 hybrid nanoparticles. The experimental and numerical results were in reasonable agreement. The discrepancy did not exceed 10.25% for maximum bending load and no difference over 5% for maximum impact load, indicating that the strengthened nanoparticle specimens were properly fabricated. Also, a significant improvement in mechanical and viscoelastic properties was achieved by incorporating hybrid nanoparticles. Flexural bending load increased by about 17 % with hybrid nanoparticles, while tear resistance increased by 27.5 % and impact resistance increased by 7.5%.
