Johnson-cook plasticity model parameters determination for Ti2ALNb intermetallic alloy
Abstract
Abstract The static and dynamic mechanical properties of Ti2AlNb intermetallic alloy were investigated through quasi-static tensile tests at room temperature and dynamic compression tests at various temperatures and strain rates. The results indicate that the Ti2AlNb intermetallic alloy exhibits low strain rate sensitivity. The flow stress of the material is governed by the strain rate and temperature, showing an increase with the former and a decrease with the latter. The Johnson-Cook (JC) plasticity parameters were determined using the LS-Opt software to minimize the least squares error between the experimental and predicted data.
