Stresses: Normal- (compression/tension), bending-, shear- and torsional stress. Free body diagrams. Modulus of elasticity. Poissons ratio. Material properties of steel, stress limitations. Stress-strain diagram of steel. Factors of safety (load- and material factors). Stress concentration ("notch"). Developement of plasticity. Fatique and fracture mechanics. Temperature stresses. Temperature expansion coefficient of various materials. Stresses in composite sections. 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). Static indeterminacy: Applying the unit load method to the computation of beam reactions and truss member forces. 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.

Assignments.

Written test of 3 hours.

For a course of 10 credits, ca. 300 hours of work in total is normally to be expected. 

Special requirements in Science

Lectures: 2 hours pr. week in the autumn parallel. Exercises: 4 hours pr. week In the autumn parallel.

The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate¿s exams as a calibration according to the Department's guidelines for examination markings.
