I am exploring different material models for a very low to low strength Siltstone (UCS = 1MPa, E50 = 300MPa) and I was thinking to consider modelling this with HS model, as unloading characteristics of this material is of my great interest. I have run a SoilTest triaxial simulation for this low strength material but the results would not match (or not even close to) the available lab test data, i.e. E50 = 200MPa. Needless to say, the Stress-Strain curve is almost linear elastic - perfectly plastic, rather than elastoplastic, which I suspect that it&#39;s due to the high shear stiffness.</p> <p>It would be great to hear your thoughts.</p> <p>Many thanks,<br />Farzam</p><div style="clear:both;"></div>Ask A Question Ihttps://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Mon, 26 Sep 2022 01:26:30 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ce7ed339-ef2c-4191-8e78-f7a72aaf91a4Ask a question in a forum.
