The measured extreme fibre strains at mid span of a simply supported beam, loaded with uniformly distributed load (Figure 3a), are: - 5000*10-6 at A and +5000*10-6 at B. Determine: (a) the bending moment on the mid-span section when the beam is made of elastic-perfectly plastic stress-strain curve as shown in Figure 4b. (b) the uniformly distributed load o when the beam section at mid span becomes fully plastic.

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.
