The algorithm is tested in two numerical examples: first, simulated data are used, in order to re‐obtain parameters for the case of damage under monotonic loading. In the second example material parameters are obtained based on experimental data for lcf‐testing of an austenetic stainless steel, thus showing a very good agreement with respect to hardening, rate and damage effects.</jats:p>"}],"publication":"Engineering Computations"},{"publication_identifier":{"issn":["0045-7825"]},"publication_status":"published","intvolume":"       136","page":"225-258","citation":{"chicago":"Mahnken, Rolf, and Erwin Stein. “A Unified Approach for Parameter Identification of Inelastic Material Models in the Frame of the Finite Element Method.” <i>Computer Methods in Applied Mechanics and Engineering</i> 136, no. 3–4 (2002): 225–58. <a href=\"https://doi.org/10.1016/0045-7825(96)00991-7\">https://doi.org/10.1016/0045-7825(96)00991-7</a>.","ieee":"R.
