Polyamide (PA) materials are extensively used in Selective Laser Sintering (SLS) for producing functional components. Among them, DuraForm PA and DuraForm GF from 3D Systems, along with PA 2200 and PA 3200 GF from EOS, are widely adopted for their favourable mechanical and thermal properties. Glass-filled (GF) composites, composed of a polymer matrix reinforced with glass particles, provide enhanced stiffness and dimensional stability compared to unfilled PA materials. This study focuses on...
Deep drawing is one of the primary sheet metal forming processes used to manufacture three-dimensional components for various industries such as automotive and household appliances. Among the major challenges associated with this process are maintaining uniform thickness distribution and reducing springback, due to their direct effect on the quality of the final product. This study aims to analyze the effect of gradually varying punch speed during the deep drawing process on thickness...

This study investigates a finite element analysis (FEA) of a dissimilar welded assembly consisting of a pure copper tube (C11000) and a brass flange, joined via the tungsten inert gas (TIG) welding process using ERCuSn-A filler metal. Numerical simulations were conducted using SolidWorks Simulation to evaluate the thermo-mechanical response of the joint under specific operating conditions. The research encompasses a transient thermal analysis of the welding process, followed by a static...
This research paper aims to study the effects of heat treatment on 14 mm reinforcing bars that are produced by the Libyan Iron and Steel Company. These operations were conducted in the quality control laboratory, and it was found that there are two types of 14 mm reinforcing bars: (G-40) and (G- 60). The difference between them is the percentage of carbon present in their chemical composition, as the percentage of carbon in the variety (G-40) ranges between 0.25% and 0.38%, and as for the...
