The Finite Element Analysis

In the present work, three natural fibres, namely jute, hemp and bamboo have been hybridized with seashell powder and polypropylene resin as biohybrid composites. Nine samples are considered for this study with various weight propositions of bamboo, hemp, and jute. The mechanical characteristics, such as the flexural, impact, and tensile strength of nine samples, are compared, and the Sample 9 shows very good results; the obtained flexural, tensile strength and impact energy of Sample 9 are 239.36 MPa, 47.84 MPa, and 18.33 J, respectively. The main reason for this is the presence of jute material and layering pattern; Sample 9 contains 60 % Jute, 20 % hemp, and 20 % bamboo; the percentage of jute is high compared to the other eight samples. Furthermore, morphological analysis and thermogravimetric analysis (TGA) have been carried out with Sample 9. While comparing the properties of with the existing dashboard material properties, they show more desirable values and thus, the compositions of Sample 9 material can be used for various vehicle parts. When the experimental results are compared with the finite element analysis (FEA) results, the experimental results match with the FEA results, and few variations are noticed.

Purpose The study aims to investigate the influence of fabric hybridization, stacking sequences and matrix materials on the tensile strength and damping behavior of jute/carbon reinforced hybrid composites. Design/methodology/approach The hybrid composites were fabricated with different sequences of fabric plies in epoxy and polyester matrix using a hand layup technique. The tensile and vibration characteristics were evaluated on the hybrid laminated composite models using finite element analysis (FEA), and the results were validated experimentally according to ASTM standards. The surface morphology of the fractured specimens was studied using the scanning electron microscope. Findings The experimental results revealed that the position of jute layers in the hybrid composites has a significant influence on the tensile strength and damping behavior. The hybrid composite with jute fiber at the surface sides and carbon fibers at the middle exhibited higher tensile strength with superior damping properties. Further, it is found that the experimental results are in good coherence with the FEA results. Originality/value The less weight and low-cost hybrid composites were fabricated by incorporating the jute and carbon fabrics in interply configurations. The influences of fabric hybridization, stacking arrangements and matrix materials on the tensile and vibration behavior of jute/carbon hybrid composites have been numerically evaluated and the results were experimentally validated.

In article present the developed methodology will allow monitoring pipeline displacements under changes in operating conditions, as well as simulating unfavorable processes (thawing of soil, formation of taliks, violation of thermal insulation). The planning of the experiment was carried out to obtain the calculated mechanical characteristics of the soil, depending on the temperature and humidity, used to calculate the stress-strain state of the pipeline. A mathematical computer model has been developed to determine the radius and temperature field of the thawing halo around the pipeline. A template for displaying experimental data for their use in the finite element analysis of pipeline displacements during soil thawing is presented.

Abstract This paper analyzes the change of brake torque during normal stop and emergency braking of elevator. Taking the permanent magnet synchronous elevator traction machine as an example, the mechanical characteristics of the brake wheel and brake shoe on the brake under emergency braking are analyzed. According to the finite element analysis and calculation results, the impact and stress of the elevator are the largest at the moment of emergency braking, reaching 270.3MPa, and the strain increases gradually. The analysis results can provide reference for the design and verification of brake wheel and brake shoe of elevator traction machine.

Use of natural fibres as reinforcement in polymeric composites has been increased during last few decades. They are potential alternatives to synthetic fibres due to their excellent properties like light in weight, biodegradable, abundant, satisfactory strength etc. Various parts of automobiles are being made by natural fibres that improved fuel efficiency and reduced emissions. The present study focuses on developing new polymer composites by reinforcing walnut shell particulate on the basis of different weight fractions. Mechanical characterization was done for the developed composites which include evaluation of tensile strength, impact strength and hardness. Different weight fractions of walnut shell particulate were used including 0%, 10%, 15% and 20%. Maximum tensile strength was achieved in case of 10% walnut shell reinforced composites. Maximum impact strength and hardness were achieved in case of 20% and 15% reinforcement respectively.

Bridging play a important role in guarantee the stability of the high-formwork support system as a whole, its arrangement location will affect the force of the frame body. This paper used the finite element analysis method to compare the bridging arrangement location under the beam with the bridging under the board which was arranged according to certain modules. the results show, the arrangement spacing of the bridging under the beam is greater than the bridging under the board, but its frame body lateral migration is smaller, sharing part of the axial force of beam bottom rod at the same time, that means the bridging under the beam is more beneficial for the stability of high-formwork support system.
