The high-order shear deformation theory and Bernoulli’s equation for the structure-fluid interface were used. To solve the equations obtained and validate the results, the Galerkin method and Abaqus finite element software were employed. The main innovation of this research is the calculation of the effective mass of the top layer and the entire sandwich cylindrical shell containing fluid using displacement field relations, their equivalent density, and indentation force due to impact. In addition, to calculate the impact force and the structure-fluid interaction, a two-degree-of-freedom model of mass, spring, and damper with the effect of the crushing resistance of the core was used. The results show that the fluid is an important and effective factor in calculating the natural frequency and low-velocity impact on the structure. The presence of fluid reduces the fundamental natural frequency of the sandwich cylindrical shell by 69%. Parameters such as core and layer thickness, length, and radius of the sandwich cylindrical shell, presence of the fluid, various boundary conditions, wave number, fiber orientation angles, velocity, and mass of the impactor are essential and influential factors in studying vibrations, impact, and optimal design of structures.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sandwich structure was divided into three layers including two thin facesheets made of a functionally graded graphene-reinforced composite and a thick core from a soft lightweight polymer foam. Five different functionally graded distribution patterns were considered for the facesheets. A refined high order theory was employed for kinematic assumptions. The transverse flexibility of the core and zero transverse shear stress conditions at the lower and upper surfaces of the plate were taken into account. The Hamilton’s principle was used to obtain the equations of motion and the analytical solutions were presented. Effects of the elastic foundation, plate geometry, and the graphene platelets properties on the natural frequencies of the sandwich plate were explored. The accuracy and reliability of the present modeling and results were examined and verified in specific cases. Results showed that reinforcing the facesheets of sandwich plates by graphene platelets increases their natural frequencies.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using software based on the finite element method, computational models were utilized to simulate the four-point bending test. Two scenarios were examined: assuming a linear stress-strain curve for the material and employing nonlinear geometric analysis. These computational simulations allowed to determine loading limits and vertical displacements. After determining the flexural stiffness, the vibration response was calculated via an analytical procedure. This investigation proved that sandwich panels with greater thicknesses and volumes of reinforcements on the plaster faces exhibited greater load-bearing capacity, smaller displacements, greater resistance to traction and compression, and greater stiffness. Notably, panel 3, which had the thickness and volume content of reinforcement in the composite faces 24.71 and 66.67% higher, respectively, than reference panel, presented the best static and vibrational responses.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The comprehensive analysis of physical and mechanical properties, such as tensile strength, impact resistance, hardness, water uptake was carried out using Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The manual hand layup technique was employed to ensure reproducible composite production. The resulting materials exhibited favorable mechanical properties, with the tensile strength and elongation balanced between jute and jack tree fibers, augmented by the reinforcing effect of the eggshell filler. Jack tree fibers significantly enhanced impact strength, contributing to the overall toughness of the composite. Hardness testing revealed higher crystallinity attributed to jack tree fibers. Water absorption characteristics demonstrated a nuanced interaction between cellulose abundance and fiber mass. FTIR spectroscopy provided molecular insights, while SEM analysis visually depicted the intricate structure of the composite. The amalgamation of jack tree and jute fibers with an eggshell filler not only enhances mechanical prowess but also aligns with global environmental efforts. This research advances sustainable composite materials, offering nuanced insights into the interplay between natural fibers, fillers, and matrices, with implications for eco-friendly solutions in diverse industries. The findings contribute to a greener, more sustainable future in industrial applications.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
