Abstract
A Monte Carlo simulation was conducted to determine the error in the determination of Weibull parameters when fiber strengths are calculated as the ratio of the experimentally-determined breaking loads and the average of the fiber cross-sectional areas. The parameters of the distribution of modified fiber strengths diverge from the actual parameters with increasing dispersion in the distribution of fiber diameters: specifically the Weibull modulus decreases while the characteristic strength increases with increasing dispersion in fiber diameters.
