dominate industrial and technological applications due to their ubiquitous existence, low-cost and ease of manufacturing. During the sheet metal operations, e.g. bending, stamping, drawing and stretching, among the various possible modes of failure, such as wrinkling, scoring, the tearing of a polycrystalline sheet metal is the most common, resulting from an uneven or exorbitant amount of plastic deformation forming a localized neck and therefore limiting the formability of the polycrystalline sheet metal. In the sheet-metal forming industry, it is therefore, of high importance that the failure of metal sheets due to localized necking must be analyzed. In 1963, a breakthrough in formability assessment…
Sheet Metal Systems When it comes to commercial and manufacturing construction, there is one roofing material that is most commonly seen: sheet metal systems. Sheet metal systems are one of the most popular commercial roofing materials in the United States because of its singular value. Sheet metal systems are cost-effective, energy-efficient, durable, and easy to find in a variety of shapes, sizes and colors. If you are looking at constructing a new warehouse or office building, or are even…
Sheet Metal Roofing If you are in the midst of planning your next new home construction or roof replacement project, you may have come across sheet metal roofing in your research. To most homeowners who do not live in major urban centers, the idea of sheet metal roofing on a residential home may seem foreign. However, sheet metal roofing is experiencing a real moment in the residential home construction world. Sheet metal roofing is exactly what it sounds like: it is a roof made-up of…

Carports are like the garage spaces you have in your houses. It functions the same way in giving protection to your cars. The only difference is that carports are not fixated. Instead, it is a portable and retractable device you can bring with you in your outdoor trips. The best carports for this generation are the ones made of metal, usually of aluminum or steel. There are also that has core panels made of insulated polystyrene foam. This is also wrapped with steel or aluminum. Most metal…
Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…
its own symbol ,atomic number ,and atomic mass. The symbol is letters of the element, atomic number is the number of protons, and atomic mass is the mass of the element. The Symbol for Calcium is `Ca’ and the atomic number is 20, and the mass number is 40.078 u. Family. The periodic table is classified into groups and every group(row) has its own properties. Calcium is in group 2 ,and this is the second most reactive group of the periodic table. Each of the elements in group 2 has two…
Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less…
that of pure copper. Copper is the main component, and brass is usually classified as a copper alloy Brass is stronger and harder than copper but not as strong or hard as steel Uses of brass metal Brass metal is used to make water fittings, screws, radiators, musical instruments and cartridge casings for firearms. Brass is a fairly strong metal but relatively malleable, so it is easily mauled into a number of different…
AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…
