Bond distribution and the size-strength relationship

Common practice to normalize the compressive strengths of spherical agglomerates of different sizes is to divide individual loads at failure by (pellet diameter)2 (cf. Section 4.1). This treatment of pellet strength data, however, assumes a uniform radial distribution of bonds within the agglomerates. That is, in the generalized relationship between load at failure and agglomerate diameter,
