Effective yield strength of a saturated porous medium with a spheroidal meso-pore and spherical micro-pores

A macroscopic yield criterion has been derived in the present work for a double saturated porous medium with a spheroidal pore at the mesocale and spherical pores at the microscale. These two types of pores are well separated at two different scales. The meso spheroidal pore saturated by a pore pres...
