The knowledge acquired is structured into four main areas: fundamental knowledge, specialized knowledge, language skills, and methods of scientific inquiry. The latter area encompasses the acquisition of methods for critical analysis, the development of abilities to formulate, synthesize, and apply scientific ideas and innovations, as well as skills for solving complex scientific problems. The program prepares doctoral students to expand and enrich their knowledge in the relevant scientific field, as well as to develop its interactions with other related scientific disciplines. In addition to specific knowledge, emphasis is placed on acquiring skills such as: using specialized literature (including that in a foreign language); systematizing, summarizing, and analyzing existing data; independently conducting scientific and applied research; and formulating and presenting results in a comprehensible, logical, precise, and accurate manner.

Dissertation topics in the Department of Machine Elements and Non-Metallic Structures are formulated around real-world problems dictated by practical needs. Doctoral students are encouraged to direct their research toward promising areas that would also benefit their own professional development following the successful completion of this advanced degree at the Technical University of Sofia. The results of the scientific research are widely published in authoritative specialized journals and presented at prestigious international conferences.

The requirements for the training of specialists holding a doctoral degree in the doctoral program “Methods for the Control and Testing of Materials, Products, and Equipment” are:
