We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Yuu0910, 

You are right about implementing unsupported material models in LSDYNA WB. 

The material card information should be modeled by performing some experiments as per the paper in the link https://www.dynalook.com/conferences/16th-international-ls-dyna-conference/constitutive-modeling-t7-1/t7-1-d-constitutive-modeling-115.pdf

or taken from the published literature sources and an example source on Mapel and Ash woods Material models are described in the link https://www.researchgate.net/publication/328971285_Characterization_of_Maple_and_Ash_Material_Properties_for_the_Finite_Element_Modeling_of_Wood_Baseball_Bats?_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6Il9kaXJlY3QiLCJwYWdlIjoiX2RpcmVjdCJ9fQ

Make sure you follow consistent units with LSDYNA WB. 

Cheers, Ram
