plane deformation, stress tensor, plasticity, elasticity, elastoplastic limit, non-uniform body. 

In the paper elastoplastic condition of plain with elliptic apertures and elliptic non-uniform bodies with biaxial strain is investigated. The flat deformation is observed. The elastoplastic limit, influence of elliptical non-uniform body on strained condition of plain is investigated.
