The kinematic hardening behavior of materials is entrenched in the automotive, aerospace, aviation, and many other industries and is becoming increasingly important. Direct effects on component life, reliability, and performance, especially for high recurrent determinate and indeterminate load up to the plastic deformation range, need to be calculated more accurately and efficiently. By further developing existing and new strain hardening models, the simulations performed in this area can lead to more optimal component design. Since the parameter sets for kinematic hardening differ depending on the material and the hardening model, this work deals with the acquisition of the softening parameters for a high-strength pipe material. In the first part, an overview of the different models, calculation methods, deviation analysis and optimization processes are given. In the experimental part, the experimental procedure is explained by using a notched flat specimen and the ARAMIS deformation measurement system. Due to the high forces, especially in the compression range, the problem of buckling is included. Finally, the further execution of the test using round specimens and the further calculation of the kinematic softening parameters by means of a simulation in ABAQUS are discussed.
