This study proposes a formula for estimating the tensile strength of solid bodies with any given particle size distribution. Based on Rumpf’s equation, it develops an equation for tensile strength that varies according to particle size distribution, packing density, and average coordination number, taking into account the capillary force between spherical particles of different sizes. By using this formula, it calculates the tensile strength differences due to particle size distribution under specific environmental conditions, demonstrating that tensile strength varies even when the median particle size is the same, due to changes in packing density and surface area per unit volume of particles according to particle size distribution.
