heal.abstract	Since explosive compaction constitutes a tool for producing superconducting materials with unique properties for advanced structural applications, the calculation of the optimal compaction parameters is of great importance. In this paper, a methodology of numerical finite element modelling in the explosive compaction technique of the YBCO superconducting powder of various geometries is reported. The information stemming from this implementation may constitute some basic conditions for the creation of numerical models of explosive loading of superconducting materials, resulting in the prediction of parameters that are difficult to measure experimentally. The evolution of the deformed shapes, the pressure, density and temperature distributions during the entire compaction process is predicted. The mechanical response of the superconducting powder was described by the modified Drucker-Prager/cap elastoplastic constitutive model, which was implemented by using explicit finite element techniques. The computational results obtained are presented and discussed, showing good agreement with the experimental work.	en
