Section outline

  • This unit emphases on state of stress at a point (general 2d system), principal stresses, biaxial direct stress, uniaxial direct stress, case of pure shear stress, Mohr’s cycle for stresses, construction of Mohr’s cycle and principal strains and strain energy due to principal stresses.

    It is essential to the understanding on what happen inside a particular body subjected to some loading conditions.

    The knowledge gain through this unit may serves a base to understand other future courses such as Soil Mechanics, Soil Dynamics, Foundation engineering, etc.

     

    ILOs:

    At the end of this unit, you will be able to:

    1. Understand compound stresses and strains

    2. Establish differences between simple and compound stresses, and simple

        and compound strains

    3. Describe Mohr’s cycle

    4. Apply data to the solution of Mechanics of Materials problems
