The paper presents the results of the theoretical and practical researches regarding the development of conceptual and experimental models specific to the determination of the safety parameters regarding the friction and impact sensitivity, whose plausibility be guaranteed through a whole range of scientific solutions characterized by validated results through numerical modeling and simulations. Designing these types of processes requires consideration, with a relative approximation, the degree of danger due to the design of fragments resulting from detonation, vibrations, pressures, tensions created in the space affected by the explosion, explosion gas generation etc. Estimating the peak values of induced requests is an essential for implementing IT solutions of previous experimentation allows the study of a large number of scenarios, the limit being mainly dependent on the time spent on computer simulations. In this context, safety research into the handling of explosives, the acquisition of experience and knowledge as well as the validation of results by comparison with previous practical experiments and those specified in the literature, become relevant and necessary requirements. Methods used to determine security parameters, analyzed by classical and IT means are relevant to the interpretation of the nature of the explosive matter in terms of their effect in terms of the effect they may have on the environment of use in the event of an explosion in accordance with the legislation in force an important indicator of classification, handling, storage and transport in the assessment and the management of the risks associated with these operations. The paper presents a series of results regarding computer numerical simulations, safety parameters (friction and impact sensitivity). The similarity of the results obtained in the case of physical experiments to determine the susceptibility of explosive substances tested to friction and impact stimuli in relation to those provided by computerized numerical simulations demonstrate the usefulness of these IT science solutions that through the ANSYS Multiphysics package provide the prerequisites for determining the safety features in the field of explosives for civilian use.
