Stregth of materials II MKBMN03018

Course content:
Generalized theorems for elastic systems. Total elastic strain energy. Generalized forces and displacements. Betti’s reciprocity of works principle. Castigliano theorem and Maxwell-Mohr method. Statically indetermined structures - Menabre’a theorem, Maxwell-Mohr method (method of forces), compatibility of displacements method. Curved bars. Some engineering problems of elasticity theory: thin-walled axi-symmetrical vessels subjected to internal pressure, bending of rectangular plates to a cylindrical surface, symmetrical bending of a circular plates, thick-walled tubes subjected to internal pressure, rotating disks. Some dynamics problems of elastic systems. Entirely elastic impact – dynamic problems. Elasto-plactic systems.

Learning outcomes:
skill of making diagrams of internal forces, calculating stresses and strains in complex loading states, formulating of strength and rigidity conditions, obtaining critical loading and designing of typical elements.
