Undrained cavity expansions in critical state soils. (English) Zbl 0885.73065

We present analytical and semi-analytical solutions for the undrained expansion of cylindrical and spherical cavities in critical state soils. The strain is finite, the initial cavity radius is arbitrary, and the procedure is applicable to any isotropically hardening materials. In all cases only simple quadratures are involved, and in the case of the Cam-Clay a complete analytical solution can be found.
