Abstract

Concrete damage plasticity (CDP) model is used to model the concrete damage through using ABAQUS software. Among several input parameters that should be defined in CDP model, the dilation angle (ψ), eccentricity parameter and tensile behaviour, have been identified as a significant influence on the finite element (FE) results for concrete modelling under static loading while limited studies examined these parameters for concrete subjected to impact load and high-strain rate. This study aims to focus on numerical modelling of impact-loaded concrete, examine and calibrate the above CDP model parameters using three-dimensional FE modelling. Several values of dilation angles, ψ, of 30 to 550 and eccentricity parameter of 0.1 to 0.2 have been used to capture the test behaviour. The model tensile softening behaviour was also investigated using three models, bilinear stress-strain, tri-linear stress-strain and stress-crack opening displacement. The FE results revealed that the value of dilation angle ranged 45-500, the eccentricity parameter and tri-linear stress-strain model of tensile softening provided better correlations with test results in terms of displacement-time plots and cracking paths.
