Two exothermic mixtures of Nb–Si and Ni–Al particles having dimensions of 5 μm×25 μm were considered. Computational experiments showed that the mixtures exhibit a classical phenomenon of thermal explosion under high rates of shearing. The threshold shear rates were found to be approximately 1.2×108/s and 8.0×107/s for the Nb–Si and Ni–Al mixtures, respectively. The ignition conditions were sensitive to the thermal boundary conditions and the computationally observed values are considered to be the upper limits. The thermal explosion results from the interaction of mechanical mass mixing and heating that were primarily caused by thinning (plastic deformation) and fragmentation. The modeling showed an interesting result: that there is a ratio of fracture strengths that maximizes the mass mixing.}, number={7}, journal={JOURNAL OF APPLIED PHYSICS}, author={Tamura, S and Horie, Y}, year={1998}, month={Oct}, pages={3574–3580} } @article{tamura_aizawa_mitsuno_kihara_1998, title={Steel powder compaction and forming analysis}, volume={34}, number={1}, journal={International Journal of Powder Metallurgy}, author={Tamura, S. and Aizawa, T. and Mitsuno, T. and Kihara, J.}, year={1998}, pages={50–59} } @inproceedings{tamura_horie_1997, title={Discrete meso-element simulation of chemical reactions in shear bands}, volume={429}, booktitle={Proceedings of the Conference of the American Physical Society Topical Conference on Shock Compression of Condensed Matter held at Amherst, Massachusetts, July 27-August 1, 1997}, author={Tamura, S. and Horie, Y.}, editor={S.
