Course content

Shear stress and shear strain. Plane stress and three-dimensional stress state. Generallized Hooke's law. Stresses in cylindrical and spherical vessels, pipes and beams. Principal stresses. Yield criteria: Tresca and Mises. Introduction to statically indeterminate systems. Buckling. Periodic motion: Undamped and damped, free and induced oscillations for systems with one degree of freedom. Idealization of structures to systems with one degrees of freedom.

Learning outcome

The subject is based on TKT4118 Mechanics 1, and these two subjects will in common provide a general basis in solid state mechanics for the student. Approx 2/3 of the subject is devoted to a continuation of the strength of materials - syllabus from TKT4118, and covers more general stress and strain analysis, statically indeterminate systems and buckling. The last 1/3 handles theory for periodic motions. (Dynamics for rigid bodies is covered by TFY4102/TFY4106 Physics).

Learning methods and activities

Lectures and exercises. If there is a re-sit examination, the examination form may be changed from written to oral exam.
