Strength of Materials I.

Lecturer:

Miroslav Sochor (gar.), Miloslav Vilímek

Tutor:

Eva Gultová, Miloslav Vilímek

Supervisor:

Department of Mechanics, Biomechanics and Mechatronics

Synopsis:

This course is to provide the ability to comprehend and analyze basic types of loading of simple machine members in order to determine their stress states and deformations. This provides tools for dimensioning the members and/or determining their allowable loading. This subject also provides the prerequisite for other advanced and special courses concerning the theory of elasticity and plasticity. Seminars are devoted to practical design and computation of simple machine elements.

Requirements:

Main therms of Statics

Syllabus of lectures:

1. Tension and compression.

2. Trusses both statically determinate and indeterminate

3. 2D- and 3D-stress state (principal stresses and planes and maximum shearing stress).

4. Strain energy for multiaxial stress state.

5. Theories of failure.

6. Torsion of circular bars.

7. Centroids, second moments of area, and products of inertia of plane areas.

8. Bending of beams (shearing force, bending moment, normal and shearing stresses in beams).

9. Deflection of beams.

10. Statically indeterminate beams.

11. Combined loading (unsymmetrical bending; bars with axial loads; bending and torsion; torsion and tension; bending and shear).

12. Design for fatigue strength (cyclic loading; S-N diagram; Smith's and High's fatigue diagrams)

13. Safety factors for fatigue strength; stresses due to combined loading.

14. Thin-walled rotational membranes.
