Abstract: A digital CT image processing based finite element method for 2-D mechanical analysis of geomaterials, is put forward. Digital image processing (DIP) is applied to convert computerized tomography (CT) image into a digital form that can be incorporated into finite element modeling. This CT discrimination based finite element modeling is used to analyze mechanical behavior of asphalt concrete indirect tensile test by taking into account the actual inhomogeneities and microstructures, especially voids distributions. The maxium tension stress appeared on the surface between voids and aggregates and the tension stress distribution along the loading axis of the sample is different.

Key words: computerized tomography (CT), digital image processing, geomaterial, finite element method
