Course detail
Dynamics III - Nonlinear and Stochastic Vibration
FSI-R3DAcad. year: 2020/2021
The students will have a basic knowledge of nonlinear and stochastic models of engineering systems and its operation and responses. They will be able to calculate a typical linearized model of these systems. They will be able to solve practical problems that can be modelled in this way.
The student will have knowledge of the chaotic operation and they will be able to analyse responses of dynamic system with random vibration or seismic excitation.

Final examination: The exam is divided into two parts. The evaluation of the exam is based on the classifications of each part. If one of the parts is graded F, the final grade of the exam is F. The content of the first part is a test, of which a maximum of 30 points can be obtained. The content of the second part is a solution of typical problems. It is possible to gain up to 30 points from this part. The form of the exam, types, number of examples or questions and details of the evaluation will be given by the lecturer during the semester. The final evaluation is given by the sum of the points gained from the exercises and exam. To successfully complete the course, it is necessary to obtain at least 50 points, where the maximum of 100 ECTS points can be reached.
