Based on the experimental-computational approach, a method for identifying deformation diagrams of elastoplastic materials by considering the inhomogeneity of the stress-strain state and large deformations was developed. Examples of the application of this method for various types of loading of the tested samples were presented: tension and torsion of cylindrical rods, kinetic indentation of a ball and a cylinder, dynamic compression of tablet samples, etc. A technique for interpolating the deformation diagram to take into account the type of stress state was proposed.
Keywords: experimental-computational approach, elastoplastic material, numerical technique, static and dynamic indentation, construction of true deformation diagrams, large plastic deformations.
Mots-clés : tension, torsion, compression
