    In common language ductility refers to the ability to be deformed without losing toughness; pliable, but not brittle. Malleable means the ability to be hammered or pressed into shape without breaking or cracking. These properties a great interest in selecting material for building things. Ductility and malleability are two aspects of the plasticity of solid materials. In metals ductility and malleability is very high due to their ability sustain large amounts of plastic deformations within the crystal

    i. Car Body Car bodies are usually made of steel or aluminium. They both have different properties and prices ranges that make it ideal. Aluminium has a lower density meaning the car will be lighter than if it was made from steel. It also doesn’t corrode easily so a car made of aluminium will last longer than that made from steel as the steel contains iron which will corrode. In saying this aluminium is much more expensive, and although it has better properties is may take the price of the car up

    occur due to the environment this paper primarily focuses on hydrogen embrittlement. Hydrogen embrittlement occurs when steel is exposed to hydrogen causing it to become brittle and crack. Hydrogen reduces load – bearing capability and reduction of ductility, there are several hydrogen sources, it can enter the material as a result of electroplating, and the main source of hydrogen in steel bridge cable wires is hydrogen gas in the atmosphere. Molecular hydrogen is dissociated, which produces atomic

    Background Microstructure refers to the arrangement of atoms in an ordered, repeating, three dimensional pattern. The microstructure of a metal is closely linked to its quality, composition, processing history and properties. Metals are typically polycrystalline where they are composed of many grains. Grains are generally unable to be seen and thus require a microscope in order to view clearly. Aside from grain boundaries, the crystalline structure of the material remains the same. Microstructures

    original positions after large inelastic deformation. It had been identified that a common bridge column failure caused by insufficient ductility which results in lack core confinement. The confined core of the concrete cross section was increased the ductility capacity intensely (Bassem Andrawes et al 2010). A common retrofitting technique used to improve the ductility capacity of vulnerable columns by using jacketing or external wraps that offer additional confinement. There are two methods for confine

    accounts mainly for ductility as well as the degree of redundancy in the structure and the strain hardening (Truby A. 2015). Force reduction factor (R) in ECP 2012 is defined for five categories of basic structural systems with total twelve subsystems for different ductility classes of building according to the type of utilized structural system .While in the EC8:2004 behavior factor (q) values are given for various materials and structure systems according to the relevant ductility classes (high or
