where is the cavity radius in the cylindrical and spherical problems [8]. It is convenient to plot the ratios and as functions of . These functions are shown in Fig. 5. The distances and are always greater than . If is much smaller than , both and are close to . The growth of with increasing ratio is much faster than that of .

4 Critical Distances in Soil

In dry granular soils such as sand, the stiffness as a function of the confining pressure is known to obey a power law with an exponent of about 0.5–0.6 [10]. Based on this fact, we consider a simple constitutive model in which the stiffness k for uniaxial deformation is a function of of the form
