Abstract Natural fibers in fiber reinforced polymer (FRP) composites are emerging engineering applications due to their high renewability and sustainability. In recent years, natural based functionally graded hybrid (FH) have been developed by combining natural‐synthetic along the thickness varying material properties. This study examines buckling postbuckling response of plain FH composites. Carbon FRP(CFRP), hemp FRP(HFRP) with stacking sequences (0/90) 4s , (−45/+45) (−45/+45/0/90) 2s ....

<title>Abstract</title> This study offers a well-organized, optimal configuration that is specially made to satisfy the many requirements of electric bikes in more favorable circumstances. Every now and then, permanent magnet (PM) machines vehicles (EVs) encounter difficulties such as large speed range action considerable field weakening at high temperatures, which can cause demagnetization. In order mitigate dangers associated with zone, we suggest implementing multi-speed transmission...

Abstract This paper presents the findings of a numerical study conducted to examine influence different structural parameters on response complete steel-free, glass fiber reinforced polymer (GFRP) dowel connector based, GFRP-concrete composite beam. The three-dimensional nonlinear analysis was carried out using commercial software package Abaqus/CAE , and damage evolution in concrete defined damaged plasticity (CDP) material model. methodology validated by comparing results against those an...

Recent research trends focus on developing bio-based (derived from agricultural byproducts) fiber-reinforced polymer (FRP) composites for structural applications. Fire resistance is one of the key issues that need to be addressed use these FRP materials in buildings. The thermal and mechanical properties constituent essentially determine fire performance (and rating) a member, vary with temperature. Further, composite such as are highly influenced by composition type fibers matrix,...

Abstract The main objective of this study is to investigate the effect combining natural and synthetic fibers on mechanical characteristics hybrid novel functionally graded composites by considering hemp as fiber carbon glass fibers. Before manufacturing, were treated with sodium hydroxide (NaOH) solution remove impurities surface. reinforced in an epoxy‐based matrix using a hand‐layup technique. volumetric fraction was 40% 60% matrix. Different types composites, such plain polymer (FRP),...

This paper focuses on the flexural behavior of masonry walls strengthened with precast engineered cementitious composite (ECC) sheet. The were subjected to out-of-plane static loading and analyzed using ABAQUS. For validation numerical results, four size 762 × 480 230 mm cast burnt clay bricks cement mortar. Out four, two ECC sheet epoxy as adhesive, remaining acted control specimens. results experimental shows that model can effectively capture nonlinear predict strength failure mechanism....

This paper presents a numerical study to evaluate the fire resistance of concrete beams and slabs incorporating natural fiber-reinforced polymers (FRP). A validated finite element model was applied carry out series studies on fire-exposed reinforced (RC) strengthened with conventional bio-based FRP composites. The calculates temperature-dependent moment–curvature relationship for various segments member at each time step, which are then used calculate moment capacity deflection member....

In this work, hybrid composite having linear gradation of carbon and glass fibers (functionally graded (FGH)) is made its material properties are compared with classical sandwich (SH) laminates, i.e., in between or vice versa. The performance FGH evaluated tensile, compressive, flexural loadings. Using analytical approach (rule mixtures), effect w.r.t. fiber laminates determined terms strength stiffness. It observed that failure specimen progressive, layer by failure, due to high ductility...

Human Papillomavirus (HPV) infection is a common viral disease with potential to cause serious health complications, including cervical cancer. This descriptive study aimed assess the knowledge of HPV among women in rural area Baghanki, Manesar, Haryana. Data were collected from 50 aged 20–60 years using structured questionnaire. Results revealed that 66% demonstrated average knowledge, while 6% had good and 28% exhibited poor or very understanding. The findings emphasize need for targeted...

The present investigation deals with carbon-fiber-reinforced polymer (CFRP) rebar manufacturing, experimental flexural and shear response of near-surface-mounted (NSM) CFRP-strengthened reinforced concrete (RC) beams, detailed parametric study NSM-strengthened RC beams using Abaqus. CFRP bars were manufactured locally the twisting technique. Parametric was performed by considering various key parameters which affect strengthening such as a bar's orientation, geometry, intergroove separation,...

This study presents the material characterization of pultruded fiber-reinforced polymer beams different sizes using experimental and analytical methods. Various tests were performed to determine properties such as Young's shear moduli tensile bending coupons beams. The stiffness measured from four-point test both is in close agreement with It shown that numerically obtained flexural response beam ABAQUS software response.
