The original paper presented an axisymmetric cone penetration model and simulations of cone penetration in saturated clay with the Mohr-Coulomb (MC), modified Cam clay (MCC), and MIT-S1 constitutive models calibrated to Boston blue clay (BBC) behavior as documented in experimental data. The two primary objectives of the paper were as follows:
- Validate the penetration model and implementation of the MITS1 constitutive model for FLAC in order to move forward with studies on intermediate soils, and
- Investigate the effects of su anisotropy on cone penetration in saturated clay.
Two discussions were submitted in response to the paper, one by Konkol and Balachowski, and another by Koutsoftas. The main discussion points were the role of strain rate effects (SRE) on conepenetration resistance (qt), aspects of constitutive model calibrations, and comparison of the simulated qt with measured qt. These are addressed in the three subsequent sections.
