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.

Question

100%

A beam of the cross section shown is made of steel that is assumed to be elastoplastic with \( E = 200 \, \text{GPa} \). The bending is about the \( z \) axis.

- The horizontal axis is marked as \( z \).
- The vertical axis is marked as \( y \).
- The centroid of the section is marked as point \( C \).
- The width of the section is annotated as \( 60 \, \text{mm} \).
- The height of the section is annotated as \( 90 \, \text{mm} \).

The residual stress is \(\_\_\_\_\_\) MPa.
