Numerical Study on Compressive Properties of Mineral Composite Material

Article Preview

Abstract:

The compressive properties of mineral composite material (MCM) are simulated by finite element (FE) method. A meso-scale 2D FE model for MCM specimen was established based on the real shapes of aggregates and their distributions in the matrix. Quasi-static compressive load was then exerted on the model, supposing no debonding exists between the matrix and aggregates and no failure occurs on their interfaces. Comparing the simulation with experimental results, it is found that the simulated stress-strain curve agrees well with the experimental one. It proved that the way for simulating compressive properties of MCM in this paper is very effective.
