# TBM120 Mechanics of Materials and Structural Engineering Basics

Credits (ECTS):10

Course responsible:Themistoklis Tsalkatidis

Campus / Online:Taught campus Ås

Teaching language:Engelsk

Course frequency:Annually

Nominal workload:For a course of 10 credits, ca. 250 hours of work in total is normally to be expected.

Teaching and exam period:This course starts in Autumn parallel. This course has teaching/evaluation in Autumn parallel, .

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.

### Learning outcome

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.
• Lectures and exercises.
• Lecturers will be available for assistance in their offices.
• FYS110
• Written test of 3 hours.

• 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.
• Assignments.
• Lectures: 2 hours pr. week in the autumn parallel. Exercises: 4 hours pr. week In the autumn parallel.
• Special requirements in Science
