Abstract:
According to the objective grading curve and filling area fraction of aggregates, numerical concrete specimen was firstly built on the basis of the advanced numerical generation method of aggregates with random shapes. And then, mesoscopic numerical simulation tests were carried out to study the damage evolution and to compare the influences of mechanical parameter distribution patterns(Weibull and lognormal distribution)on the mesoscopic strength of concrete specimen. Numerical result shows that Weibull distribution pattern is more active to reflect the discrete mechanical properties of concrete.
