Materials Testing

Holders: Assist. Prof. Kek Tomaž

Subject description

Course objectives

Within the course students acquire the advanced knowledge and skills that are required to carry out destructive and nondestructive tests of materials and structures. Students will overview the concepts, principles, and methods employed for different material tests. Emphasis is on inspection methods employed to ensure structural integrity of broad class of engineering materials and structures. Review of surface integrity parameters will be presented and overview of corrosion processes and corrosion testing, crack propagation measurements, surface wear and residual stress measurements.

Objectives and competences

This elective course develops technical expertise to assess the behaviour of materials built into a device or structure from the viewpoint of the selected manufacturing process. Students will get competences of surface integrity yielded by different manufacturing processes and ensuring the required quality for the operation of a device. Students will get knowledge of inspection methods that are important technical component of general engineering and design.

Objectives are also the basic principles and importance of various NDT and NDE methods, fundamentals, discontinuities in different product forms, applications, limitations of NDT methods and techniques, standards and specifications related to non-destructive testing technology. General overview of corrosion processes and corrosion testing, fatigue, crack propagation measurements and surface wear.

Intended course learning outcomes

Students will analyze the possible application of different techniques of destructive and non-destructive testing methods for different problems in the field of evaluating the integrity of structures and materials. They will compare and choose the appropriate method for specific task. Investigate the possibility of solving the problem by applying the existing software and /or write own program. Students will be able to test some mechanical properties with unconventional use of nondestructive methods.
