Elastic-plastic relations which are subjected to the constraint of incompressibilily, that is pertinent to undruined behavior of soils, are assessed and compared with the relations for drained behavior. The tangent relations for mixed control variables (total stress and strain components) are established explicitly. The criterion signalling plastic loading, and elastic unloading, is considered in particular. A criterion for unique response, as expressed in terms of elastic and plastic loading, is formulated as a condition on the particular plastic modulus that corresponds to undrained behavior. Stability is discussed in terms of appropriate critical values of the plastic modulus. It appears that, for a frictional material, dilatancy has a stabilizing effect whereas contractancy may be destabilizing compared to drained behavior.
