OS1605 Bending Deformation Property of Cast-Shape Memory Alloy for Brain Spatula Subjected to Temperature Variation
Bibliographic record
Abstract
In order to develop a brain spatula or a brain retractor made of a shape memory alloy (SMA), the bending deformation characteristics of the brain spatula of TiNi SMA made by the precision casting were discussed. The results obtained can be summarized as follows. (1) The maximum force obtained from the cyclic three-point bending test increases from first cycle to tenth cycle and a rate of increase is low after tenth cycle. (2) In the cyclic three-point pulsating-plane bending, recovery strain and maximum force change slightly except for initial cycle. Residual strain disappears after heating. (3) The fatigue life in pulsating-plane bending both with heating and cooling and at room temperature is longer than that in alternating-plane bending. (4) If bending direction of brain spatula is decided as pulsating, the change of bending deformation property is small during cyclic use, and long-life is achieved.

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.
