Strength of Materials II
This course complements Strength of Materials I and deals with fundamental concepts of Structural Mechanics, namely plastic bending, shear, torsion, yield and failure criteria for ductile and brittle materials, and column buckling. As such, it provides knowledge to other courses on analysis and design of structural systems.
