摘要：
Plane strain and uniaxial compression tests are generally used for characterization of a material constitutive behavior during hot forming. Interpretation of the results obtained by such tests is complicated by flow inhomogeneity occurring in a specimen volume and temperature variations. Inverse analysis is an effective instrument allowing one to take these factors into account and obtain more accurate constitutive equations of a material. In this study the constitutive behavior of HC420LA steel was examined by plane strain and uniaxial compression testing on Gleeble 3800. Finite element simulation of the tests was performed in order to evaluate the flow inhomogeneity and its effect on stress-strain curves obtained as a result of testing. Inverse analysis was used to correct the initial Gleeble data and obtain accurate constitutive equations of the material.
