摘要：
Based on the available experimental data, dependences of true stress on true strain under dynamic loading for titanium alloys VT6, OT4, OT4-0 are constructed, and parameters for Johnson-Cook model are determined. Simulation results for deformation and fracture of fan case of aircraft engine at highspeed collision with the fan blade simulator in LS-DYNA software package are presented.
