This study investigates the ballistic response of laminated composite plates using numerical simulations. Numerical simulations were carried out to determine thick Kevlar/epoxy plates, commonly used in body armor. These impacted at velocities between 100 and 1000 m/s. The parametric impact caused by cylindrical projectile is undertaken obtain an estimate for limit velocity, energy absorbed plate, contact duration. effect mass diameter on velocity was also studied. results obtained hereby are...
Abstract The uniform mixing of particles is crucial in many industrial applications. In industries, most granular materials are nonspherical, with ellipsoids being a common deviation from the sphere. study employs DEM model to investigate binary mixture vibrated packed bed fixed amplitude and frequency. explores behavior coarse fine particles, one particle ellipsoid aspect ratios (0.25–3.0) other subdomain index quantifies mixing. mixtures determined by ratio particles. efficiency indicated...
Segregation, the opposite of mixing, poses a common challenge in granular systems. Using rotating drum as basic mixing equipment, fundamental focus this study is to quantify undesirable segregation. The impact particle level parameters (size, density, their combination, mass fraction) and system (filling %, rotational speed, baffle) on segregation index within first assessed using discrete element method (DEM). Later, machine learning (ML) model applied conjunction with DEM expand fill...
The effect of the shape particles on mixing and segregation is studied in a vibrated packed bed mixer. Binary mixtures (unequal sized) four types nonspherical glass (cube, prolate, oblate, elongated needle) with different aspect ratios are used alongside spherical particles. overarching goal to explore nonsphericity granules (particles > 2 mm) food pharmaceutical industries. experimental studies analyze behavior based particle (shape size) system (frequency amplitude) parameters. results...
The current study aims to investigate the segregation in dilute phase transport through a pneumatic conveying system. Different types of nonspherical particles such as ellipsoids (prolate and oblate), cube, elongated needles are mixed with spherical influence non-sphericity. Experiments performed examine effects particle system parameters size, shape, gas velocity, solid loading rate on segregation. A unique decreasing trend is observed for shape large oblate > prolate needle small cube....
