Evaluation of the ISA-Hypoplasticity Constitutive Model for the LEAP-2017 Project
Bibliographic record
Abstract
In this work the capabilities of the ISA-hypoplasticity model for the simulation of a sandy material are carefully analyzed. The ISA-hypoplasticity model is based on the hypoplastic model by von Wolfferdorff (1996), extended by the intergranular strain anisotropy (ISA) concept by Fuentes and Triantafyllidis (2015). The model is able to simulate monotonic and cyclic loading, and has been recently modified to consider the cyclic mobility effect. Within this work, a calibration procedure has been conducted to determine the material parameters of Ottawa F65 sand and a set of experiments showing monotonic and cyclic loading has been simulated. This work is embedded within the liquefaction experiments and analysis projects (LEAP), which seeks to assess and improve the current numerical tools for prediction and evaluation of soil liquefaction phenomena.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
