Experimental and modelling investigation of vibration‐induced fluidization in sheared granular soils
Bibliographic record
Abstract
Abstract Vibration‐induced fluidization (ViF) is a phenomenon where a granular medium completely loses shear resistance or flows continuously under vibration and thus behaves like a fluid without invoking remarkable excess pore pressure. This paper attempts to investigate ViF through a series of modified triaxial tests and using an extended shear‐transformation‐zone (STZ) model that correlates macroscopic plastic deformation to the motion of internal mesoscopic weak spots (i.e., STZs) within granular materials. The test results revealed that the ViF may take place when the vibration is applied at either critical or non‐critical states. Theoretical analyses using the extended STZ model show that the vibration intensity required to cause fluidization increases linearly with the initial quasi‐static shear stress level at which vibration is imposed. The model results are generally consistent with experimental data, indicating that the extended STZ model has a desirable performance in simulating the fluidization of granular soil subjected to quasi‐static shearing and vibration simultaneously.

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.
