Prediction of the mechanical behavior of the Oporto granite using Data Mining techniques

► Granite weathering characteristics and physical properties vs weathering degree index. ► Uniaxial compressive strength and the modulus of elasticity of granitic rocks. ► Artificial neural networks (ANN) and support vector machines (SVM). ► Free porosity (N48), dry bulk density (d) and ultrasonic velocity (v). ► SVM model gave the best results with N48 and v as input variables.
