About Course

The course aims to cover fundamentals of mechanics of materials to know the behaviour and properties of engineering materials when subjected to different loading and boundary conditions.

Description

Mechanics of materials also known as strength of materials is the branch of solid mechanics /continuum mechanics, which deals with the study/behaviour of deformable bodies. Mechanics of materials is fundamental subject in mechanical/civil engineering and has also specific application in many other areas such as in health care/medical to understand the anatomy of living beings, dental prostheses and surgical implants. This basic study will be helpful for advance topics of solid mechanics such theory of elasticity, theory of plasticity, fatigue and fracture mechanics which deals with the initiation and propagation of cracks in solid materials. Thus, attending this course mechanical and civil engineers will gain theoretical knowledge of mechanics of materials and solve solid/structural problems adopting appropriate theory and formulas while solving solid/structural mechanics problems.

What Will I Learn?

  • Gain fundamental knowledge of mechanics of deformable solids including stress, strain, stress – strain relations, theories of failure and energy methods.
  • To know the different types of stresses and strains developed in the member subjected to axial, bending, shear, torsion and thermal loads.
  • To understand the concepts of calculation of forces and moments in solid/structure for different loading and boundary conditions.
  • To expose the students to the concepts of strain energy, work done and then determining the stresses, strains, in axial bars, beams, columns, struts and shafts.
  • Examine the properties of deformable bodies and apply the basic concepts and theoretical laws and derived formulas in solving solid/structural mechanics problem.
  • To know behaviour and properties of engineering materials.
  • To understand the stresses developed in bars, compounds bars, beams, shafts, and cylinders.
