I am using Radioss and Hypermesh to simulate some bulk materials like sand, rock, soid, ... Now my problem is I don't know what the material card I can use for simulate. Can you help me?
Hi,
Material Laws 10,21 (Drucker Prager) are suitable for rock and soft soils. Material Law81 (for geomaterials) is an advanced material law from Drucker Prager criteria which can be used for any geomaterial.
Please go through the Help Menu on these material laws.
