Numerical Model Building and Optimization of Concrete Based on the CT Images and Digital Volumetric Speckle Photography

Abstract:

In recent years, the research on the mesostructure of the concrete by using numerical simulation has been a hot topic. Mesoscopic research would contribute to reveal the concrete cracking failure mechanism. In this paper, the aggregate, the mortar , the interface and the pore are segmented based on CT images . With the aid of Mimics software, the numerical model for ANSYS is built. Besides this, the concrete specimen under uniaxial compression is scanned by using micro-CT in situ. The volumetric images under different loadings are acquired. By using digital volumetric speckle photography (DVSP) method, interior 3D deformation is obtained. Combined with the experiment results, the numerical model is optimized. Based on the optimized model, mesoscopic mechanics of concrete is analyzed by using numerical simulation.
