Products Detail
Large-Diameter Split Hopkinson Pressure Bar System(ZDSHPB-50/80)
 |
The ZDSHPB-50/80 Split Large-Diameter Hopkinson Pressure Bar System is specifically developed for the dynamic mechanical characterization of non-metallic materials under high strain-rate impact loading. Featuring large-diameter pressure bars (Φ50 mm and Φ80 mm), the system is particularly suitable for testing rocks, concrete, geomaterials, and other coarse-grained or large-sized specimens that cannot be accurately evaluated using conventional SHPB systems. |
 |
Core PositioningSuitable for large-sized and coarse-particle material testing. Based on one-dimensional stress wave theory, the system accurately determines the dynamic stress-strain response, strength, deformation behavior, and failure mechanisms of materials subjected to impact loading, providing reliable experimental data for geotechnical engineering, construction materials research, and protective structure design.
