In this study, the effect of the Lode angle on failure and plasticity is considered, and a new Lode angle function on plasticity is developed. Meanwhile, a new temperature coefficient function is proposed in this model, and the application of the model is extended to the range from room temperature to 650°C. The tensile specimens of different shapes have been designed to calibrate the parameters of the model. The tensile tests are carried out on the in situ micro-tensile machine.
