Prerequisites
PRP_1 Flexibility and strength I.
Condition for registration of the subject of the Flexibility and Strength of 2 is the successful completion of the subject Flexibility and Strength 1.
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives supported by learning outcomes
To acquaint a student with the basics of general theory of elasticity, solution of problems of elasticity and strength on bodies of special shapes, dimensioning components under cyclic loading, fracture mechanics and dynamic deformation and stress analysis of one-dimensional linear continuum.
Learning outcomes
After completing the subject, student is able:
- to describe mathematically spatial strain, define boundary states, and formulate strength conditions
- to solve strength and deformation problems on bodies of special shapes
- to dimension the components during cyclic loading
- to work with the basic concepts of fracture mechanics
- to apply modern matrix methods in solving the modal and spectral properties of the continuum
- to create mathematical models for solving the dynamic stress and deformation analysis of a one-dimensional continuum
