Abstract

Presented in this paper are the computational results on deformation of austenitic steels at different strain rates and temperatures. To describe the dynamic response of steels a relaxation constitutive equation was developed using a thermomechanical physically-based model. On the base of experimental data on uniaxial loading of new steels in the range of strain rates from 0.001 to 500 s-1 the model parameters were derived, and dynamic responses of the steels were predicted, within the range of strain rates up to 8000 s-1 and at initial temperatures from 77 to 600 K, with the strains exceeding 60% being calculated. A plane stress analysis was performed using the ABAQUS finite-element procedure with a user-defined subroutine developed. The physically-based model was developed to take into consideration an evolution of the dislocation density and the Lüders band propagation. Plane strain simulations of thermomechanical response of HSLA-65 steel were carried out for different strain rates and initial temperatures at the initial stage of compression (strain <10%).
