TBM120 Mechanics of Materials and Structural Engineering Basics

Stresses: Normal- (compression/tension), bending-, shear- and torsional stress. Free body diagrams. Modulus of elasticity. Poisson's ratio. Material properties of steel. Stress-strain diagram of steel. Factors of safety (load- and material factors). Stress concentration ("notch"). Temperature stresses. Temperature expansion coefficient of various materials. Force- and moment-diagrams. Introduction to the unit load method, i.e. the theory and developement of beam- and truss deflection formulas. Buckling (radius of gyration, Euler column, real column, buckling length, slenderness ratio). Computation of bending- and shear stresses at any chosen point of a beam section.

The students should upon completion have an understanding of: Linear forces and moments (including torsion), stresses, equilibrium of bodies (free body diagrams), deformation, strength of materials, elasticity, column buckling. The students should be able to compute the first moment of an area, the moment of inertia and the section modulus, draw shear- and moment-diagrams for beams, be able to apply the unit load method for beam and truss deflection computations and statically indeterminate beam reactions and statically indeterminate truss member forces, be able to develop stress formulas and know how to apply those formulas.
