We analyze initial states of stress and deformation produced in an elastic diphase medium by forcing independent, arbitrary distortion fields, which do not necessarily fulfil the static or geometric constraints in both phases. External prestressing consists mainly in introducing the both phases such distortion fields that the fields of initial stress and deformation induced in one (prestressed) phase cause a desirable adjustment of the distribution of the final states of stress and deformation in this phase. These states are a sum of the corresponding initial states and states caused by external load. The other phase plays a role of the prestressing one. Some examples of an optimal control of the final states of stresses in the prestressed phase are discussed.
