Contact Foam
A ball and a block are modeled out of solid elements. *MAT_SOIL_AND_FOAM_FAILURE keyword allows the specification of a material which loses its ability to carry tension when failure pressure is reached. See example contact_rubber for a similar deck with block made of rubber. Download is available in the download section of this document.
