Automatic identification of anisotropic yield function parameters
In high-strength aluminum sheets and highly anisotropic steel sheets, the representation capability of the yield function has a significant impact on simulation accuracy.
By using MatYLD, the parameters of advanced yield functions such as Yoshida, Yld2000-2d, and Gotoh can be easily identified from experimental results.

Support for advanced yield functions
Parameters of advanced yield functions, such as Yoshida, Yld2000-2d, and Gotoh, can be identified.
The parameters of various anisotropic yield functions can be calibrated from a limited set of experimental data, including uniaxial tensile test data in three directions of the sheet (flow stress and yield stresses: σ0, σ45, σ90; r-values: r0, r45, r90) and equi-biaxial tensile stress (σb).

Graph plotting for better understanding of material behavior
Using the identified or user-specified parameters, graphs of yield surfaces representing material behavior, as well as uniaxial flow stress and r-values, can be generated.
These visualization features provide useful graphs for deeper understanding and evaluation of material behavior.
