Abstract:
Based on the mesoscopic random aggregate model and brittle-damage constitutive model, the influences of random parameters, such as elastic modulus, tension-compression strength and their combinations on the macro tension-compression strength of specimen were studied. Results show that separately considering the random distribution of elastic modulus and strength, more reasonable tension-compression damage curve of specimen is obtained by utilizing the product of the strength and elastic modulus as integrated random parameter of the meso-element. Furthermore, the correlation coefficient is introduced to reflect the relationship between the strength and elastic modulus, the obtained numerical result shows a good coincidence with the experiment result.
