Investigation of Material Behavior of TRIP Steel by Macro and Micro Multiscale Simulation

Abstract:

Transformation induced plasticity (TRIP) steels is a kind of low-alloying high strength steel with good combination of strength and plasticity. To investigate the material behavior of TRIP steel, the multiscale simulation method was used in this paper. Through the investigation we can see that, multiscale simulation model of TRIP steel can be setup by combining finite element and microscope technology together, and the simulation results agree with the experimental results greatly. Both for uniaxial tension and biaxial tension, the micro stress distribution was unevenly for the difference of material behavior of bainite, ferrite and retained austenite, which create local stress concentration, and for uniaxial tension and biaxial tension, the stress distribution of biaxial tension was relative average, for the boundary condition biaxial tension was a kind of relative even boundary condition, the stress on different direction was balance.
