Abstract

fetched live from OpenAlex

Mechanical metamaterials are made to display characteristics that are not present in regular materials.Recent advances in alternative structures, including inclined beams, curved beams, shallow shells, Origamis, and shellulars, have made it possible to attain bistability and multistability as novel features.There are still two unsolved concerns about the use of multistable mechanical metamaterials to create electrical systems, mechanical memories, and deployable structures.First, is it possible to programme mechanical instability?Second, how can we tune mechanical properties of materials at the post-fabrication stage?Understanding the snapping sequences and changes of the elastic energy in multistable metamaterials is essential to finding the answers to these problems.Here, we represent multistable metamaterials as a chain to be transformed into the desired shape by applying a mechanical stimulus at a specific location on the external boundary of the metamaterial.A continuous path with all conceivable configurations and snap-back released energy is found for the snapping chain.It is found that the number of possible configurations depends on the order of the instability forces.We thoroughly elicit the mechanics of continuous force/energy-displacement curves and reconfiguration sequences and demonstrate how the progrmmable snapping chain can be utilized to create mechanical sensors/memories with sampling and data reconstruction functionalities.

Not 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.
