Summary: Three-dimensional photoplastic analysis is employed in modelling of forming processes such as upsetting, piercing, axtrusion, drawing, bending and bulging. The polycarbonate is applied as a model material. Influence of the contact friction to the state of strains in permanent deformed model was studied.

Keywords: photoplasticity, optical methods of strain analysis

Research goals: a) Determination of the state of strains in two/dimensional models during sheet forming operations (with special attempt to hzdrostatic expanding). b) The experiments of the forming with flat tools or with tools for die forming,should produce free surface crack, internal crack or die contact surface crack. It will make possible to determine the state of strains near the crack. c) It could bee contribution to better understanding of the model material behaviour in the critical yones of forming.
