A metal bar AB of length L is held between rigid supports and is heated non-uniformly in such a manner that the temperature increase AT at a distance from end A is given by (see figure). The material has modulus of elasticity 2E and the expression AT=- ΔΙx2 31² coefficient of thermal expansion. The compressive stress in the bar is A a TI

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
