A numerical study of chemical degradation effects on elastic-plastic behavior of sandstone
In this paper, an elastic-plastic damage model is first proposed for a class of semi-brittle rocks. This model is then applied to investigate effects of chemical degradation on mechanical behavior of a red sandstone. Experimental data obtained from three groups of samples, respectively, immersed in water and two acid solutions will be analysed. Chemical degradation effects on both elastic modulus and compressive strength will be discussed in term of the solution acidity. The relationship between the solution acidity and chemical damage will be established.
