    Journal PaperComputers in Biology and Medicine , 2021 March 2, {Pages 104303 }

    Abstract

    Little is known about the impact behavior of composite fixation plate used in the fracture healing of long bones diaphysis. Hence, this study examined polypropylene composite fixation plates using different glass fibers and measured their biomechanical responses under axial impact loading experimentally and numerically. Short randomly oriented, long unidirectional prepregs and fiber yarn of glass were considered as reinforcements, and fixation plates were fabricated through two different heat-compressing and 3D printing processes. Furthermore, assessing the fixation plate structures impact behavior was carried out using in vitro impact test and finite element analysis (FEA). Impact damping behavior, damage mechanisms, and stress and strain

    Abstract

    The current study investigated the influence of incorporation of graphene nanoplatelets (GNPs) on quasi-static behavior of composite and fiber metal laminate (FML) panels. The unmodified and modified composite specimens and FML panels with 2/1 configuration were fabricated using a hand lay-up method and investigated through a quasi-static punch and indentation testing. The two sets of tests were conducted with a flat-ended indenter and the loading conditions were the same for all samples, except support spans which were varied. Following experimental testing, possible damages at the punch region were closely investigated and localized and global damages were observed. The results revealed that adding 0.2?wt% GNPs improved the strength and f

    Abstract

    In this study the energy absorption of elastomeric foam-filled aluminum honeycomb under quasi-static compression loading and low velocity impact was experimentally investigated. Commercially available Al honeycomb made of Al5052 H38 filled with elastomeric polyurethane foam was used as the specimens. Pure polyurethane had a shore hardness of 30A and to make it foam, different volume fraction of glass microballoon was added to it and a novel material was synthesized that simultaneously had the properties of elastomers and foams Energy absorption of the specimens were evaluated by different parameters such as peak load, crushing load and absorbed energy. Also, the effective failure mechanisms were fully discussed. The results showed that the

    Abstract

    The paper investigates the addition of Nano-Al2O3 powder (alumina, Average Particle Size: 20 nm) on the characteristics of the Medium Density Fibreboards (MDF) made by the forest fibers. Some important physical, mechanical and quasi-static properties of the panels were measured according to the standard test methods and apparatus. Different percentages of alumina powder (0, 1, 2, and 3 weight percentage (wt.) based on the solid content of resin) were used and panels were made in three thicknesses (5, 10 and 14 mm). The experiments showed that the resultant properties of the new composites were improved. The greatest increase in Modulus of Elasticity (MOE) was achieved when 1% wt. alumina was added to the samples. Addition of alumina up

    Abstract

    The aim of the present study is to investigate the effect of introducing an elastomer layer into conventional fiber metal laminates on their perforation resistance. Natural compounded rubber as elastomeric media and glass/epoxy composite were sandwiched in between two layers of aluminum 6061-T6 and then the resulted structure was perforated by a 10 mm diameter hemispherical projectile at different impact velocities. Residual velocities were recorded by a high speed camera via a shadowing technique. Results showed that an elastomer layer located nearer to frontal face had a better energy absorbing performance due to load spreading; besides, by increasing the impact velocity the elastomer performs more efficiently because of the elastomer dam

    Abstract

    Human being has always been looking for optimal use of his surrounding materials that has been able to invent various structures through getting inspired by nature. Some of these structures are lattice structures. Due to their lower weight, high compressive strength and high stiffness, lattice structures are widely used in various applications, including energy absorbers. A new type of lattice structure is auxetic structures that have a negative Poisson’s ratio due to their geometric structure. This characteristic has caused auxetic structures to have unique properties such as shear strength, indentation resistance, and high-energy absorption. In this study, the experimental and numerical investigation of in-plane uniaxial quasi-static lo

    Abstract

    This paper aims to investigate the performance of an aluminum–rubber composite plate under impact loading. The impact resistance of the plate has been evaluated using both experimental and numerical methods. The experimental tests were carried out using gas gun at velocities of 75, 101, 144 and 168?m/s. The energy absorption of composite plates has been closely examined for all samples. The effect of rubber layer positioning either on front face or on back face of the aluminum plate was also evaluated. It was found that the composite plate with rubber on front face provides higher performance to absorb the energy. In parallel to the experiment, a finite element model was created using the finite element software LS-DYNA to simulate the re

    Abstract

    In this work, an experimental investigation of the high velocity impact resistance of syntactic foam core composite sandwich panel has been undertaken. The syntactic foams filled with ceramic microballoons of three different sizes and three different volume fractions. Also, to enhance the matrix strength of the foam core, some specimens reinforced with nano particles. The high velocity impact tests have been carried out using a light gas-gun and a 10?mm blunt-head steel projectile and the ballistic limit was measured. The Impact behavior and the failure mechanisms are thoroughly investigated and also the absorbed energy during projectile perforation was correlated to the damaged area of specimens. The test results show that the ballistic re

    Abstract

    This paper experimentally investigates the behavior of sandwich beam with auxetic core subjected to low-velocity impact loading. Two types of sandwich beams with different topologies of auxetic cellular cores were produced. Furthermore, a test procedure involving a cylindrical impactor was developed, and a parametric study was designed and performed. The results revealed that, at the same level of impact energy, the peak load decreased by increasing the re-entrant angle would make the auxetic sample with the highest re-entrant angle an ideal candidate for protective applications. However, in other applications where the structure needs to be protected from damage at a higher level of impact energy, the auxetic sample with the lowest re-entr
