Course description and aims

This course focuses on the mechanics of solids. Topics include mathematical preliminaries – summation convention, Krönecker delta, alternating symbol, vectors and Cartesian tensors; stresses, traction vector, equations of equilibrium, strains, compatibility conditions, material symmetry and Hooke’s law, solution schemes in elasticity, elastostatic plane problems.

The fundamentals of solid mechanics is important and is essential for the study of engineering.
Students learn the basics of mechanics of materials and will be able to solve some problems in engineering.

Student learning outcomes

By completing this course, students will be able to:
1) Understand index notation used in equations in any subject area.
2) Understand stresses and strains.
3) Understand linear elasticity.
4) Understand how to formulate and solve some fundamental problems in mechanics of solids.


Vectors and Cartesian tensors, stresses, traction vector, equations of equilibrium, strains, compatibility conditions, material symmetry and Hooke’s law, solution schemes in elasticity, elastostatic plane problems

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Most of time in the class is devoted to fundamentals and the rest to advanced contents or applications. To allow students to get a good understanding of the course contents and practical applications, problems related to the contents of this course are given as homework assignments. Solutions to homework assignments are reviewed in the class.
