Automatic English translation:
I was told that MAT_Wood can be installed using the following method. Definition method ・Right-click the part for which you want to define *MAT_WOOD under the geometry → Insert → Select command ・Select the keyword (LS-DYNA) and paste the *MAT_WOOD keyword However, I don't know where to look for the material card that was in the screenshot. I would appreciate it if you could let me know. Thank you for your support.

Hello,
If I understood the question correctly, you’d like to know where to find the keyword format for *MAT_WOOD to then insert it as a keyword snippet in Workbench LS-DYNA.
To do so, one option is to use keyword manager in LS-PrePost software to create the material card (please refer to the screenshot below that shows the environment of LS-PrePost). Double-click on 143-Wood and then enter the properties of your material. Once you’re done, go to File à Save keyword.
After you open the saved keyword file, the MAT_WOOD card is accessible and can be copied into the Workbench LD-DYNA using the procedure you described in your message.

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

Hi! Armin.
Thank you for teaching me how to create keywords using LS-PrePost.
I'll try it out right away. -

Hi ! Ram Gopisetti
Thank you for providing the literature on the keywords and the links to them.
I'll try to set the material properties while referring to this.
