This course introduces the student to complex and the manipulation of complex numbers.
Structural action types, approximations in structural analysis, axial stresses: Stresses and strains in one-dimensional structural elements: lateral strain and Poisson’s ratio, strain energy from normal stress and shear stress;
Temperature Stresses; strain behaviour of material, properties of areas, moments of area; Element subjected to general stresses and strains in two dimensional structural systems: Principal stresses and straws, strains energy from normal and shear stresses, Mohr’s stress circle, Mohr’s strain circle;
Relationships between the elastic constants bending in beams: the bending relationship, the general case of bending, asymmetrical or skew bending, combined bending and axial loading; Shear stresses in beams: shears stress in open and closed sections and shear center;
Composite beams: bending and shear stresses in beams of dissimilar materials.
