Modified Cam-Clay Calibration and Python Constitutive Model

Year: 2025
Status: Graduate coursework
Category: Grad Courses
Tools: Python, Triaxial CIU and CID data

Context

Calibrated a Modified Cam-Clay model for Bangkok clay and implemented it as a standalone constitutive model in Python.

Approach

Calibrated the Modified Cam-Clay parameters (the slope of the critical state line and the compression and swelling indices) from consolidated undrained (CIU) and consolidated drained (CID) triaxial tests, then implemented a Soft Soil Model in Python with a Mohr-Coulomb failure surface.

Outcome

Reproduced critical state behavior with the implemented model. Specific calibrated parameter values are held back from this public page pending verification.
