摘要

通过能够实时记录细观特征的原始方法获得的固体对冲击载荷响应的实验结果与连续介质力学局部平衡概念中传统的弹塑性过渡表示相矛盾。基于非平衡统计力学的冲击脉冲时空相关性的非局部数学建模允许将获得的实验数据统一到冲击波现象的新物理表示中，其中变形的介观载体是相互作用的波包。对所研究材料的微观结构研究表明，在三个冲击速度范围内，材料的变形规模不同，这是材料宏观性能的原因。

Nonlocal Transfer Mechanics in a Dynamically Deformed Medium. Wave Concept of the Mesoscale

Experimental results on the response of solids to shock loading obtained by the original method capable of real-time recording of mesoscopic characteristics contradict the conventional representation of elastic-plastic transition within the local equilibrium concepts of continuum mechanics. Nonlocal mathematical modeling of spatiotemporal correlations in a shock pulse based on nonequilibrium statistical mechanics allowed uniting the obtained experimental data within the new physical representation of shock wave phenomena where the mesoscopic carriers of deformation were interacting wave packets. Microstructural investigations of the studied materials reveal different scales of deformation in three ranges of shock velocities, which are responsible for macroscopic properties of materials.
