Verification of metal members and plates under compression and under bending

The aim of this thesis is to investigate the differences between steel and aluminium alloy in different cases. In particular, it will focus on the principal forces in construction such as compression and bending study the differences between these two materials and determine why steel is more commonly used instead of aluminium alloy. Aluminium alloy is a chemical element with symbol ``Al´´ and atomic number 13. It is silvery white and generally not soluble in water. It is the third most abundant element on Earth and makes-up about 8% by weight of the Earth’s solid surface. This metal presents the advantage that it is covered by a layer than can protect against the rust. One of the advantages of aluminium alloy is that it is covered by a layer that can protect against rust. In addition, it is much lighter and therefore cheaper to transport than other materials. Aluminium alloy also doesn’t change its characteristics during recycling. The process can repeat indefinitely and it can make objects with 100% aluminium alloy recycling with the same properties. Steel is an alloy of iron and carbon. These two components are in a huge amount over the world which helps in the production. Alloys with higher than 2,1% carbon are known as cast iron, because they are not malleable even when hot. Steel has a high density (7850 kg/) and can be welded. One disadvantage of this material is corrosion because the iron rust increasing its volume, causing cracks in the surface that makes possible corrosion progress until completely consumed pieces.Outgoin
