Description

technical field [0001] The invention relates to a solid material impact technology for civil engineering, in particular to a multi-directional high-energy high-speed electromagnetic force impact intelligent control test device and method. Background technique [0002] In the field of civil engineering, the mechanical responses of materials and structures under impact loads are significantly different from those under static loads. In engineering and other practical problems, impacts can cause serious damage. Impact involves a wide range of issues (for example, the mechanical response characteristics under impact loads are the basis for establishing dynamic constitutive relations, mechanical analysis and reasonable engineering design, and are also the basis for material models and material property data in various simulation technologies), Therefore, the physical and mechanical behavior test of materials and structures under impact load has become an indispensable technical m...
