Objetivos

It is intended that the students acquire basic skills and knowledge in the field of Mechanics of Materials: (i) know the definition and physical meaning of the internal stress matrix components and the strain matrix components, as well as Hooke’s law; (ii) know the physical meaning of Young modulus and Poission coefficient; (iii) evaluate strain and tension matrixes from results obtained with strain rosettes; (iv) evaluate stresses, strains and displacements in tridimensional frame structures built by prismatic frames (homogeneous and heterogeneous) under axial forces and torsion. In particular, it is intended that students develop the ability to adapt to new situations and properly analyze the results.

Métodos de ensino e atividades de aprendizagem

Theoretical lessons are used to expose the new concepts and some straight forward examples are shown, stimulating critical thinking of the students. Practical lessons are used to apply the concepts to increasing complex exercises, some of them solved by the students independently.There will be continuos assesment comprising 2 tests during the semester.
