基于三维Hopkinson杆的混凝土动态力学性能研究
Dynamic behavior of concrete under static triaxial loading using 3D-Hopkinson bar
摘要
Abstract
A type of 3D-Hopkinson bar dynamic testing system for investigating the dynamic behavior of concrete and rock under static triaxial loading was developed.The hydraulic servo control system employed in the testing system could provide independent triaxial pressure up to 100 MPa,and the split Hopkinson pressure bar employed in the impacting direction could provide dynamic loads.The dynamic responses on six faces of the cube specimen can be recorded by six bars in three dimensions,the lateral deformation states of the specimen under dynamic loading were obtained and analyzed by using this novelty Hopkinson bar.The dynamic compressive behaviors of C30 concrete under different static triaxial loading were investigated.关键词
