A circular aluminum alloy [E = 70 GPa; a = 22.5 × 10-6/°C; v = 0.33] pipe has an outside diameter of 265 mm, a wall thickness of 11 mm, and a length of 4.6 m. The pipe supports a compressive load of 640 kN. After the temperature of the pipe drops 35°C, determine: (a) the axial deformation of the pipe. (b) the change in diameter of the pipe. Answer: (a) d = i mm AD= i mm

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.
