    Introduction The Charpy Impact Test, invented in 1900 by Georges Augustin Albert Charpy, is a comparative test that measures the energy absorbed by a test specimen under an impact load. The test specimen is usually notched across one of the larger dimensions on the opposite side of the impact area. [1] The Charpy Impact Test is commonly used to determine the relative or impact toughness of a material and this test is used in quality control applications due to the fact that the test is fast and relatively

    (ductility) of the joint decreased due to the post weld heat treatment. • From the results of the Charpy V-notch impact test, it is found that the maximum CVN value in as welded condition of low heat input combination is 115 Joule, and it is increased with the post weld heat treatment. • Comparing the joints welded with two different heat inputs, concluded that the ultimate tensile strength (UTS) and impact toughness of the welded joints decreases with increases the heat input.

    At 11pm on the 16 January 1943, the 152m long T2 tanker 'Schenectady' broke in two amidships while lying at the outfitting dock in the constructor's yard in Portland, Oregon, USA. The temperature of the harbor water was about 4°C and the conditions were still. The air temperature was approximately -3°C and the winds were light. The failure was sudden and accompanied by a report that was heard a mile away. The fracture extended through the deck, the sides of the hull, the longitudinal bulkheads and

    Titanic was the largest ship in the world. It was about 900 feet long and weighted 46000 tons. On April 14, 1912, the titanic collided with the iceberg and sank in three hours. The colliding caused the damage which was nearly 300 feet of the hull, the collision allowed water to flood six of sixteen major watertight compartments. However, the sixteen watertight did not work very well. There were about 2200 passengers and crew on the ship, and more than 1500 died. There are many reasons caused this

[8-10] studied the mechanical properties of tensile, flexural, impact and water absorption tests were carried out using banana/epoxy composite material. Thiruchitrambalam et al. (2009) [5] studied the effect of alkali and SLS (Sodium Lauryl Sulphate) treatment on Banana/Kenaf Hybrid composites and woven hybrid composites. Thermosetting

  • TIG Welding

    1472 Words  | 3 Pages

    Welding is a process used to join metal parts by producing a coalescence, called a weld, at a joint. Advances in welding technology have opened the way for innovative designs in structures and machinery. Of modern welding processes, the greatest number fall under the general classifications of arc welding, gas welding and cutting, resistance welding, and brazing. Tungsten Inert Gas (TIG) welding is one of the arc welding methods. This method is suitable for many kinds of metals, but especially

    materials that better suit a specified use. [8] Tensile tests are simple, relatively inexpensive, and fully standardised. By pulling on something, you will very quickly determine how the material will react to forces being applied in tension. As the material is being pulled, you will find its strength along with how much it will elongate and one of the more basic tests is to determine stress – strain relationships. [10] A simple uniaxial test consists of slowly pulling a sample of material in tension
