This study conducts numerical and experimental analyses to the parameters affecting deep drawing of symmetric low-depth products, such as die geometry, punch movement, cushioning. The methodology proposed in this paper is applied on a frying pan manufactured out AL99.9%. finite element model (FE-model) developed using LS-Dyna© an experiment carried validate FE-model. results have shown minor deviation 3.5% 0.92% for maximum pressing load thickness, respectively. validated FE-model then...
This paper presents an integrated simulation system that is employed in order to evaluate the static and dynamic performance of a milling machine. The discusses design consideration evaluation system, creates based on finite element technique, applies it case study, results. Obtaining such reliable model could replace many experimental tests must otherwise be carried out each time parameters affecting cutting conditions are changed. Modeling meshing various machine elements including...
Nanotechnology is a cross-disciplinary field, which involves the ability to design and exploit unique properties that emerge from man-made materials ranging in size 1 greater than 100 nm.A self- nanoemulsifying drug delivery system fairly similar liquid lipid dosage form designed for oral composed of oils, surfactants possibly cosurfactants or cosolvents.Felodipine calcium channel blocker (CCB). It acts primarily on vascular smooth muscle cells by stabilizing voltage-gated L-type channels...
This paper presents a simulation system designed to evaluate the static and dynamic performance of machine tools. The design considerations evaluation are discussed is then employed in order compare between various categories milling machine's structure adapted for end operation. identified terms loop stiffness both x y directions, mode shapes, frequency response function (FRF) at tool center point (TCP). advantage such reliable model that it could replace many experimental tests must...
Tube end closing is a metal forming process that replaces welding processes while tubes ends. It depends on deforming rotating tube using roller, and therefore, it also called spinning. The involves many parameters like contact depth, roller inclination angle, diameter, mandrel curvature, rotational speed. This study develops finite element model (FE-model) for this validates through experimental results. numerical results have shown minor deviation of 1.87%. FE-model then employed to carry...
Objective of research: To reveal and asses probable change in fetal cardiac physiological function pregestational diabetic gestations. Research design: We performed a prospective research study 31 gestations between 22 weeks’ gestational age full term, who had diabetes. All women recruited the glycosylated hemoglobin lower than 6.5%. involved an early sonographic confirmation age. Doppler blood flow via mitral tricuspid valves were every 4 weeks using pulsed wave machine with 3.5- or 5-MHz...
Single point incremental forming, SPIF, is a forming process that has great potential application in sheet metal industries.SPIF capable of producing medium size batches complex shapes with low cost as it requires no die.This study explores the potentials integrating computer aided manufacturing, CAM, and finite element analysis, FEA, to obtain virtual model realistically simulates SPIF process.The simulation been carried out using LS-Dyna4.3© software while circular rectangular taper...
Recently, studies have focused on optimization as a method to reach the finest conditions for metal forming processes. This study tests various techniques determine optimum single point incremental (SPIF). SPIF is die-less process that depends moving tool along path designed specific feature. As it involves parameters, based experimental would be costly, hence finite element model (FE-model) developed and validated through results. In second phase, statistical analyses response surface (RSM)...
