Abstract EN
Improvement of the efficiency of the inverse analysis (IA) for various material tests was the objective of the paper.
Flow stress models and microstructure evolution models of various complexity of mathematical formulation were considered.
Different types of experiments were performed and the results were used for the identification of models.
Sensitivity analysis was performed for all the models and the importance of parameters in these models was evaluated.
Metamodels based on artificial neural network were proposed to simulate experiments in the inverse solution.
Performed analysis has shown that significant decrease of the computing times could be achieved when metamodels substitute finite element model in the inverse analysis, which is the case in the identification of flow stress models.
Application of metamodels gave good results for flow stress models based on closed form equations accounting for an influence of temperature, strain, and strain rate (4 coefficients) and additionally for softening due to recrystallization (5 coefficients) and for softening and saturation (7 coefficients).
Good accuracy and high efficiency of the IA were confirmed.
On the contrary, identification of microstructure evolution models, including phase transformation models, did not give noticeable reduction of the computing time.
