A test never seen before: a 120 mm mine inside our shelter

The test parameters were specifically selected so that the energy concentration was directed inward: the shelter had no bottom, which allowed avoiding partial wave attenuation by the soil and maximising the conditions to those of a directed internal explosion. This approach provides clear answers to two key questions: whether the shell can withstand peak pressure and whether the walls are perforated by the impact of debris.

The results confirmed the high strength of the structure. Although the surface received multiple dents and ‘pixels’ from the impact of debris, no punctures were found – the metal retained its integrity. There was a slight bend in the lower edge of the frame, which was due to the absence of a bottom during the test; with a standard bottom, such deformation would not have occurred. In general, there were no fractures or destruction, only local plastic deformations.

Conclusion: The Safe shelter frame with 20 mm walls demonstrates a reliable level of protection against internal directed explosive impacts and debris – the structure withstands peak pressures and prevents penetration, which is critical for preserving life and equipment. We are continuing a series of tests to confirm the performance in various scenarios and are preparing a detailed technical report based on the results.
