greetings of the day sir. when i am using HS model for the clay soil the value given to Eoed, E50 and Eur not accepted by the software. it showed the value of Eoed is low. and recommend another value of Eoed. here i am attaching the screenshots of this.
Dear Shailja,
A similar question has been posted before. Please check it here: Hardening Soil Model - Typicial relationships between E50, Eur, and Eoed
I hope it helps.
