Solid Mechanics, Basic Course

Valid for: 2018/19

Decided by: PLED M

Date of Decision: 2018-03-27

Main field: Technology.

Compulsory for: M2, MD2

Language of instruction: The course will be given in Swedish

The aim is to achieve such a knowledge within solid mechanics that every Master of Mechanical Engineering is expected to possess.

Knowledge and understanding

For a passing grade the student must

- have the ability to understand and apply the principles of classic solid mechanics.

Competences and skills

For a passing grade the student must

- have achieved the knowledge that is necessary for participation in the various advanced courses within solid mechanics.

Judgement and approach

For a passing grade the student must

- be able to analyse, evaluate and design commonly encountered construction elements.

The content of the course is given by the description of the separate courses.

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)

Assessment: Both parts (AKI and AKII) of the course include written examinations and grades are given for each part. In order to achieve a final grade, it is required that the laborations and projects are completed and approved.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.

Parts

Code: 0117. Name: Solid Mechanics, Basic Course I.

Credits: 7,5. Grading scale: UG. Assessment: See general description in the beginning. Contents: The course treats uniaxial stress and deformation analysis with application to design wih respect to allowable stresses and deformations in bars under axial loads, beams under bending loads, and circular bars under twisting loads. The basic concepts of normal and shear stress, normal and shear strain are defined. Based on measurements on uniaxial test pieces idealized constitutive models are formulated, which exhibit elastic, plastic and viscoelastic behaviour. The difference between statically determinate and indeterminate problems are discussed with respect to the solution methodology, and the need for deformation conditions at statically indeterminate problems is paid attention. Elementary stability theory for axially compressed struts is discussed, and design with respect to the Eulerian elementary cases is treated.

Code: 0217. Name: Solid Mechanics, Basic Course II.

Credits: 7,5. Grading scale: UG. Assessment: See the description in the beginning. Contents: The uniaxial concepts from AKI are first generalized, i.e. the general elastic boundary value problem is formulated (this comprises the generalized stress and strain state, Hooke's generalized law, the general equilibrium equations and the corresponding boundary conditions). As examples of solution or the general elastic boundary value problem, torsion of beams with non-circular cross-section and the response of axisymmetric discs are treated. Then the theory of strain gauges is given and the practical application is illustrated in a laboratory task. As design criteria for structural and mechanical components, yield criteria, fracture mechanics and fatigue are considered. Then a systematic matrix approach for analysis of truss structures is given and the principle of virtual work is introduced. Finally, an introduction to the dynamic response of simple structures is given.

Required prior knowledge: FMAB30 Calculus in Several Variables, FMEA30 Engineering Mechanics.

The number of participants is limited to: No
