BSc in Civil and Environmental Engineering

014104 – Strength of Materials 1

Course Objectives

This course builds on the principles of statics mastered in the course “Introduction to Engineering Mechanics” and will introduce the students to the fundamentals of Mechanics of Materials. This subject covers basic concepts of solid mechanics and mechanical behavior of materials, including stress-strain relationships, beam bending, stress transformation and stability of columns. Structural behavior will be analyzed, along with the material and geometric contributions to the behavior of structures.
