Continuing the CU Solid Mechanics I, the main objective is the study of solid mechanics. In particular, the study of particular cases of plane stress states is continued, in order to analyze stresses and strains in situations with temperature variations, in bended beams of open thin wall sections and in torsion of bars with thin-walled closed sections. From the deformation and displacements in the supports, hyperstatic problems will be solved. The main strength criteria are also addressed. Loading situations where the elastic limit is exceeded will also be addressed, considering the bilinear elastoplastic model. Geometric nonlinearity and equilibrium instability are also discussed. The law of conservation of energy is also discussed. In particular, energetic methods will be used to calculate displacements in structures. Thus, it is intended to deepen the techniques of structural design.
