Abstract
The mechanical behavior of engineering materials, whether of natural or artificial origin, varies with their internal structure. As the uniaxial strength σ u is commonly used to characterize basic responses to external loading, it is of value to evaluate the effect of porosity n on the magnitude of σ u . The authors first review some existing relationships developed and applied to quantify the influence of n on uniaxial strength, in compression (σ c ) and in tension (σ t ). A new general formulation, applicable to various materials over a wide range of porosities, is then proposed. Using experimental data from different sources, the validity of this new relationship is demonstrated and briefly discussed.Key words: uniaxial strength, compression, tension, porosity, porous media, experimental results, soil, rock, concrete.

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 it
