It’s commonly used for conventional metals, along with *Mat_Plastic_Kinematic. It’s an elasto-plastic material with an optional plastic strain threshold, and can also be modeled as strain rate dependent. 

You can read more details about Material models in the material manual which you can open through the LS-Dyna manager or here is an older version:
