Course Contents

Introduction to Strength of Materials

Explain the importance and review the material related to the development of correct free body diagrams. Then define the terms stress and strain and differentiate between normal stress, shear stress and bending stress. Explain the mechanical properties and their role to the strength of materials. Introduce the philosophy behind design and each design approach and also the role and the importance of the safety factor. Finally explain thermal effects and strain energy.

Tension, Compression and Shear

Understand general concept on Strength of Materials (Tension, Compression). Explain in detail the concept of normal stress and strain. Define the term Linear Elasticity and discuss in detail the Stress-Strain curve. Present the Hooke’s law, Young’s modulus and distinguish the Ductile and brittle materials. Define the Poisson’s ratio and explain its significance. Also present Shear Stress and Strain, Shear Stress and Strain Curve and the Shear modulus.

Stress and Strain Analysis

Analyse of Stresses and Strains in structures. Those include the Plane Stress, Principal Stresses and Maximum Shear Stresses. Present the Mohr’s Circle for Plane Stress and the Hooke’s Law for Plane Stress. Finally present the concepts of Triaxial Stress and Plane Strain.

Stresses in beams

Get familiar with the method for analysing pure Bending and Nonuniform Bending. Present the Curvature of a Beam the Strains in Beams (Longitudinal, Normal, Shear) and also the Beams with Axial Loads.

Torsion

Know the definition of Torsional loads and determine the deformations of a Circular Bar. Present the Circular Bars of Linearly Elastic Materials, the Stresses and Strain in Pure Shear and also the Relationship between Moduli of Elasticity E and G.

Buckling of Columns

Understand the definition of Buckling and Stability for Columns with Pinned Ends and for Columns with different Support Conditions.

Planned learning activities and teaching methodsThe course is delivered through theoretical lectures in class. The lectures present to the student the course content and allow for questions. Part of the material is presented using visual aids. The aim is to familiarize the student with the different and faster pace of presentation and also allow the instructor to present related material (photographs, videos, etc.). The learning process is enhanced with the requirement from the student to solve relevant examples. Besides from the notes taken by students in class, all of the course material is available through the class website and also through e-learning platform. Finally the instructor is available to students during office hours or by appointment in order to provide any necessary tutoring.
