The main objective of the course is to introduce students to various experimental methods used in technical practice. The subject is divided into two related parts. In the first part, the students are familiar with the basics of vector calculus, orthogonal transformation, eigenvalue problem of discrete Fourier transform. The practical lessons are designed in the form of using acquired knowledge to solve concrete examples on the above mentioned topics by means of MATLAB software.
The second part of the subject is focused on signal processing, strain gauge measurements, optical methods - photoelasticimetry and non-destructive methods (NDT) - ultrasonic testing, acoustic emission testing, dye penetrant inspection and magnetic particle testing.
