Modeling The Creep Behavior Of Wood Cantilever Loaded At Free End During Drying
Bibliographic record
Abstract
A new approach to modeling the creep behavior of a wood cantilever loaded at free end under constant moisture content and under drying conditions is developed.This approach is based on equilibrium equations of cantilever beam theory and allows the computation of stress, strain, and displacement fields through the thickness without any assumption on stress distribution.The analysis is restrained to a modified Burger model that takes into account a moisture content change in wood, although it can be extended to any type of rheological model.In constant hygrothermal conditions, the computed stress field is the same as the one based on equations of elastic cantilever.In drying conditions, a moisture gradient takes place through the thickness, and thus, a nonlinear stress distribution appears and the location of the neutral axis moves away from the geometrical center of the cross-section.The main advantage of the proposed approach is that it can be used to simulate experimental creep bending tests in the presence of moisture content gradients.Accordingly, bending tests should be appropriate to identify both viscoelastic and mechano-sorptive creep parameters.

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.
