Summary of the subject: The discipline "Modeling and degradation of products, optimization of their properties" introduces students to modern methods of modeling and optimizing the properties of materials and products using computer-aided design systems. It also characterizes the behavior of materials under different load conditions: static, dynamic, re-replaceable, high-temperature); characteristic features of various types of destructive surfaces and ways to prevent the destruction of products; influence of internal and external factors on fatigue, creep, wear, corrosion of materials; describes methods for protecting metals and alloys from the negative effects of the external environment
Studying the discipline, students acquire practical skills in working with the CES EduPak module of a specialized materials science software product from Granta Design, master the basics of using modern software for the rational choice of materials and technological approaches for manufacturing products, predicting and optimizing their properties, taking into account economic indicators.
The discipline teaches to predict the behavior of materials under operating conditions; evaluate the behavior of materials under the action of an aggressive environment; establish the type of corrosion damage and justify possible ways to increase the corrosion resistance of metals; use acquired knowledge for expert analysis; create safe conditions for the work of parts; rationally choose suitable materials for parts and products; form the necessary operational properties of materials.
It forms the student's understanding of the need to take into account the fundamentals of sustainable development in the development of new materials and the creation of products based on them.

Порядок та критерії виставляння балів та оцінок: 100-88 points - certified with an “excellent” grade - High level: the student demonstrates an in-depth mastery of the conceptual and categorical apparatus of the discipline, systematic knowledge, skills and abilities of their practical application. The mastered knowledge, skills and abilities provide the ability to independently formulate goals and organize learning activities, search and find solutions in non-standard, atypical educational and professional situations. The applicant demonstrates the ability to make generalizations based on critical analysis of factual material, ideas, theories and concepts, to formulate conclusions based on them. His/her activity is based on interest and motivation for self-development, continuous professional development, independent research activities, implemented with the support and guidance of the teacher. 87-71 points - certified with a grade of “good” - Sufficient level: involves mastery of the conceptual and categorical apparatus of the discipline at an advanced level, conscious use of knowledge, skills and abilities to reveal the essence of the issue. Possession of a partially structured set of knowledge provides the ability to apply it in familiar educational and professional situations. Aware of the specifics of tasks and learning situations, the student demonstrates the ability to search for and choose their solution according to the given sample, to argue for the use of a particular method of solving the problem.
