Computational assessment of the microstructure-dependent plasticity of lamellar gray cast iron – Part III: A new yield function derived from microstructure-based models

  • A new yield function for lamellar gray cast iron materials is proposed. The new model is able to describe the results of recently performed microstructure-based finite-element computations that resolve the three dimensional yield surface of three different gray cast irons. The yield function requires only the yield stress in tension and compression of the respective material as model parameters.A new yield function for lamellar gray cast iron materials is proposed.

The yield function requires only the yield stress in tension and compression of the respective material as model parameters. Furthermore, the algorithmic formulation of the new model is assessed for numerical robustness and efficiency.show moreshow less
