On the Creep Analysis of Rock Masses by Using a Viscoelastoplastic Model
Bibliographic record
Abstract
Creep in rock masses is typically described as the gradual deformation that occurs when loads are applied for long durations at varying temperatures.This process, which may result from chemical reactions in susceptible environments, leads to instabilities and catastrophic strength degradation in the rock masses.An example of a susceptible environment is crystalline and sedimentary host rocks or rock salts in deep geological repositories.Such environments are subject to the long-term transfer of radionuclides at high temperatures.This research is focused on the study of creep in several numerical examples under different loading conditions.The simulations are conducted using finite element analysis of viscoelastic and viscoelastoplastic materials.The former uses the known Waste Isolation Pilot Plant (WIPP) model, and the latter incorporates a newly proposed viscoelastoplastic model that integrates the WIPP and Mohr-Coulomb (MC) models.Results are verified with available closed-form and numerical solutions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
