The composite contains an even number of reinforcing fiber families, which are divided into pairs of families. In each pair of the families, the fibers are made of the same material and are laid symmetrically with respect to the directions of principal stresses in the composite. The constituents of the reinforced composite are isotropic and have different tensile–compressive yield strengths. The mechanical behavior of composition constituents was described by the associated flow rule of an ideal rigid-plastic body with piecewise quadratic and piecewise linear yield curves in the space of principal stresses. The influence of approximation parameters of yield curves of composition constituents in the principal stresses and reinforcement parameters on the shape and dimensions of the yield curves of compositions was studied. It was demonstrated that the plastic flow in a fibrous medium is associated with the calculated yield curves of compositions.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139397218","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 study aimed to evaluate the use of coarse and fragmented tire rubber waste, without chemical treatment, as a replacement for fine aggregate in geopolymeric mortar specimens. The central composite design, coupled with the response surface methodology, was used to determine the optimized values for compressive strength, water absorption, void index, and specific gravity. X-ray diffraction and scanning electron microscopy were used to characterize the geopolymeric mortar specimens. The optimized parameters for the best results were 1% replacement of fine aggregate with tire rubber waste, 0% coarse rubber, and approximately a 6-day curing time. This combination resulted in optimal values of 17.75 MPa for compressive strength, 10.48% for water absorption, 18.58% for void index, and 1.77 g/cm3 for specific gravity. The experimental validation of the models had an error of less than 10%.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139396933","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}

Friction stir welding (FSW) is a solid-phase welding technology characterized by low temperature and large plastic deformation. It is basically not affected by the crystal structure and physical-chemical properties of materials and can realize polymer and aluminum alloy-specific materials quality connection. This paper presents a comprehensive review of the current advancements in FSW between polymers and aluminum alloys with a focus on optimizing welding parameters, joint formation, defect identification, and mitigation. The results showed that the most important details are that high rotation speed combined with low welding speed that is beneficial to increase welding heat input, improve joint forming and mechanical properties, and form aluminum riveting structure. Welding defects are the main reason for the low FSW performance of polymer and aluminum alloy heterogeneous structures. To improve the forming and load-bearing capacity of heterogeneous structures, welding tool structure design, surface pretreatment, and welding structure optimization can be utilized.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139398657","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}

High-speed bullet impact tests of fiber-reinforced resin matrix composite laminates were carried out at 25, 160, and 200°C, and the impact limit speed Vc was calculated using the test results. The test results showed that Vc of carbon-fiber-reinforced resin matrix composite laminates decreased with increasing ambient temperature. On this basis, a dynamic failure model of fiber-reinforced resin matrix composites was established considering the influence of ambient temperature. A VUMAT user subroutine was also developed to embed the failure model into the finite-element analysis software package. Then, the high-speed impacts of composite laminates at different temperatures were simulated numerically. The magnitude of Vc was predicted by the bisection method.

The neural network estimated the homogenized parameters of composite materials linked to finite-element (FE) models. An advantage of this approach is its flexibility in obtaining model parameters, which often have no physical interpretation. Moreover, the joint application of ANNs to estimate the model parameters and FE simulations to obtain the global mechanical behavior of SFRC is an innovation. An experimental database was constructed from the tests available in the literature and provided the ANN input data: the water-cement ratio, the fiber volume fraction, and the diameter and length of steel fibers. The outputs were Young’s modulus, the tensile strength, and the fracture energy of the composite. Three different networks were trained for each output dataset. The ANN configuration consisted of an input layer with four nodes and an output layer with one node. Blind tests with five experimental test sets checked the solution accuracy, presenting relative errors lower than 10%. Finally, a FE model of a direct tensile test was built, adopting the parameters obtained through the workflow. The load–displacement curve of the numerical solution showed a good agreement with the experimental curve, and peak–load errors were smaller than 5%.","PeriodicalId":18308,"journal":{"name":"Mechanics of Composite Materials","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139102934","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}
