Reply To: How to view “crack patterns” after solution

Hello Fernando, 

The D3CRACK file is usually used with Winfrith concrete model (*MAT_084/085). 

 

For MAT_280 the crack directions are displayed ploting history variables. Please see Keyword Manual II - MAT_280 Remarks 9 and 11 https://lsdyna.ansys.com/manuals/. 

History variables are explanied here: https://lsdyna.ansys.com/ale-history-variables/ 

Please see this paper about laminated glass modeling: https://www.dynalook.com/conferences/13th-european-ls-dyna-conference-2021/composites/tatarsky_arup.pdf/view

Thank you,

Alex
