To provide basic knowledge about the representation of the stress and strain state in a solid body subject to applied forces and torques. Apply that knowledge to the study of linear members with applied forces and torques, axial and transversal. Topics such as statically indeterminate problems; buckling of the beam due to axial loading or the application of some energy methods, are also covered.


It is strongly recommended that students have obtained frequency/approval for the discipline Applied Mechanics I.

Subject matter

Study the Mechanical Behaviour of Materials and work out practical cases concerning to Stress and Strain of prismatic members, in the elastic domain, including the following main subjects:Elasticity: Concept of stress – Normal and Shearing stress – and related Strains; Tensile test of metallic materials; Residual stresses and deformations; Factor of Safety.Representation of plane stress in Mohr''s Circle for stress; Principal Directions and Principal Stress; Relation between Axial Strain and Transversal Strain. Superposition Principle; Multiaxial Loading; Generalized Hooke''s law. Young''s modulus and Poisson''s ratioDimensioning of mechanical members; Dimensioning of Bolts, Pins and Rivets connections

Teaching method

Theoretical Lectures:

Oral explanation of subjects. A review of subjects addressed in the previous lecture will be done at the beginning of each lecture. At the end of each lecture will be done a summary of the main themes given.

Practical Lessons:

Resolve problems, examples and practical cases, with the pupils. The problems solved are concerned to subjects addressed in the previous theoretical lectures.

Evaluation method

  • 3 Practical Mini-Tests (T1, T2, and T3) and final Exam (E)
  • Approval: Classification in Exam E ≥9,5
  • Approval and freedom of exam: (T1+T2+T3)/3 9,5
