Abstract
The authors have proposed a visco-elasto-plastic suspension element method using a non-continuum model to simulate dynamically the fracture behavior of concrete. In this paper, the constitutive law used in the analytical method is improved to express the deformation behavior of concrete under repetitive compressive loading. A constitutive law proposed contains viscous and elastic elements for shear after failure. Some analyses of concrete under repetitive compressive loading were carried out by using the method. As a result, the deformation behavior of concrete under repetitive compressive loading is clarified. Kaiser effect of acoustic emission is also confirmed by this numerical analyses.
