Geostatic stress state

A geostatic stress field procedure:

  • is used to verify that the initial geostatic stress field is in equilibrium with applied loads and boundary conditions and to iterate, if necessary, to obtain equilibrium;

  • accounts for pore pressure degrees of freedom when pore pressure elements are used, and accounts for temperature degrees of freedom when coupled temperature–pore pressure elements are used;

  • is usually the first step of a geotechnical analysis, followed by a coupled pore fluid diffusion/stress (with or without heat transfer) or static analysis procedure; and

  • can be linear or nonlinear.
