Synopsis:

Learning outcomes of the course unit The course will acquaint students with the principles of explosion resistance of buildings using advanced methods of modeling explosion phenomena, air shock wave propagation through space and its interaction with structures, explosion and shock wave propagation by structural elements and impact structures. The course provides information that is not included in other subjects of compulsory study plans. The course is focused on the use of numerical modeling in this area. It is modeling by nonlinear dynamics using explicit solver based on the finite element method with fluid dynamics (ALE), particle models (PBM) as well as simplified semi-empirical methods. In the part focused on numerical modeling is also highlighted the issue of inputs into software tools. Possibilities and pitfalls of determining the inputs needed for individual models are explained, with the main focus on the characteristics of materials in terms of shock wave propagation. Emphasis is also placed on a suitable way of verifying the results by means of model verification and validation. The experimental program is closely related to verification. Within the course, the student will become acquainted with the possibilities of testing structures, possibilities of testing structures on a smaller scale, etc. The last part of the course is the design of protective measures for structures where it is necessary to consider the explosion or shock load.
