To this end a sensitivity analysis consistent with the integration scheme presented previously is performed in a systematic manner, both for strain and stress controlled experiments. 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.}}, author = {{Mahnken, Rolf and Johansson, Magnus and Runesson, Kenneth}}, issn = {{0264-4401}}, journal = {{Engineering Computations}}, keywords = {{Computational Theory and Mathematics, Computer Science Applications, General Engineering, Software}}, number = {{7}}, pages = {{925--955}}, publisher = {{Emerald}}, title = {{{Parameter estimation for a viscoplastic damage model using a gradient‐based optimization algorithm}}}, doi = {{10.1108/02644409810236920}}, volume = {{15}}, year = {{2002}}, } @article{45429, author = {{Mahnken, Rolf and Stein, Erwin}}, issn = {{0045-7825}}, journal = {{Computer Methods in Applied Mechanics and Engineering}}, keywords = {{Computer Science Applications, General Physics and Astronomy, Mechanical Engineering, Mechanics of Materials, Computational Mechanics}}, number = {{3-4}}, pages = {{225--258}}, publisher = {{Elsevier BV}}, title = {{{A unified approach for parameter identification of inelastic material models in the frame of the finite element method}}}, doi = {{10.1016/0045-7825(96)00991-7}}, volume = {{136}}, year = {{2002}}, } @article{45432, author = {{Mahnken, Rolf and Stein, E}}, issn = {{0965-0393}}, journal = {{Modelling and Simulation in Materials Science and Engineering}}, keywords = {{Computer Science Applications, Mechanics of Materials, Condensed Matter Physics, General Materials Science, Modeling and Simulation}}, number = {{3A}}, pages = {{597--616}}, publisher = {{IOP Publishing}}, title = {{{The identification of parameters for visco-plastic models via finite-element methods and gradient methods}}}, doi = {{10.1088/0965-0393/2/3a/013}}, volume = {{2}}, year = {{2002}}, } @article{45425, author = {{Johansson, Magnus and Mahnken, Rolf and Runesson, Kenneth}}, issn = {{0029-5981}}, journal = {{International Journal for Numerical Methods in Engineering}}, keywords = {{Applied Mathematics, General Engineering, Numerical Analysis}}, number = {{11}}, pages = {{1727--1747}}, publisher = {{Wiley}}, title = {{{Efficient integration technique for generalized viscoplasticity coupled to damage}}}, doi = {{10.1002/(sici)1097-0207(19990420)44:11<1727::aid-nme568>3.0.co;2-p}}, volume = {{44}}, year = {{2002}}, } @article{45430, author = {{Mahnken, Rolf and Stein, Erwin}}, issn = {{0749-6419}}, journal = {{International Journal of Plasticity}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, number = {{4}}, pages = {{451--479}}, publisher = {{Elsevier BV}}, title = {{{Parameter identification for viscoplastic models based on analytical derivatives of a least-squares functional and stability investigations}}}, doi = {{10.1016/s0749-6419(95)00016-x}}, volume = {{12}}, year = {{2002}}, } @article{45428, author = {{Mahnken, Rolf and Stein, Erwin}}, issn = {{0045-7825}}, journal = {{Computer Methods in Applied Mechanics and Engineering}}, keywords = {{Computer Science Applications, General Physics and Astronomy, Mechanical Engineering, Mechanics of Materials, Computational Mechanics}}, number = {{1-2}}, pages = {{17--39}}, publisher = {{Elsevier BV}}, title = {{{Parameter identification for finite deformation elasto-plasticity in principal directions}}}, doi = {{10.1016/s0045-7825(97)00008-x}}, volume = {{147}}, year = {{2002}}, } @article{45426, author = {{Mahnken, Rolf}}, issn = {{0749-6419}}, journal = {{International Journal of Plasticity}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, number = {{11}}, pages = {{1111--1137}}, publisher = {{Elsevier BV}}, title = {{{Aspects on the finite-element implementation of the Gurson model including parameter identification}}}, doi = {{10.1016/s0749-6419(99)00029-7}}, volume = {{15}}, year = {{2002}}, } @article{56467, author = {{Thiel, Ansgar and Teubert, Hilke and Kleindienst-Cachay, Christa}}, journal = {{Sportunterricht}}, number = {{3}}, pages = {{68--72}}, title = {{{Was erwarten Grundschullehrerinnen und -lehrer von einer „Bewegten Schule“?
