Aim
The aim of the course is to provide a well-founded but practice-oriented knowledge about the materials, application possibilities and testing and qualification methods of mechanical and electronic applications. An important aim of the course is to acquaint students with the possibilities and methods of modeling material properties. Modern structural materials, stainless steels. High entropy alloys. Conductive properties of metallic materials, superconductors and semiconductors. Magnetic properties, soft and hard magnetic materials of mechatronics. Polarization mechanisms of insulating materials, electrically conductive properties. Modern The subject discusses the so-called. intelligent materials that can serve as actuators, as well as some sensor base materials.

He constantly monitors his work, results and conclusions. Student continuously expands your knowledge about magnetic materials, polymer insulators, sensors and intelligent materials. Open to the use of information technology tools. Student seeks to become familiar with and routinely use the system of measurement and data processing equipment required to perform magnetic measurements. Student seeks to learn and routinely use models that describe material properties. Student develops your ability to provide accurate and error-free problem solving, engineering precision and accuracy. Student publishes its opinions and views without offending others.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, student works with fellow students to solve tasks. Student makes a responsible, well-founded decision based on his analyzes. Student is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
The subject is taught in the form of lectures. The lectures basically introduce the competence elements of the knowledge to the students using the technique of frontal education. The lectures review the state-of-the-art materials of mechanical applications, their degradation processes and their modeling possibilities. The lectures are complementary to the available written study materials, and individually they are not sufficient to achieve adequate preparation.

General rules
Learning outcomes are assessed on the basis of a year-end written performance measurement (exam). To pass the exam, you must achieve at least 40% of the points. On the one hand, the exam asks for the necessary lexical knowledge, and on the other hand, it focuses on the application of the acquired knowledge, thus focusing on problem recognition and solution. During the performance evaluation, a specific problem related to its applications must be solved or make suggestions for solutions. The selected material or material model must be justified by the candidate using his / her knowledge of the subject.
Assessment methods
