1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Nondestructive characterization of elastic constants for laminated composites is critical for certifying manufactured composites before their use in various engineering applications. This paper presents an ultrasonic guided wave-based inversion approach, which leverages (i) noncontact laser Doppler vibrometry, (ii) frequency-wavenumber analysis, as well as (iii) an inversion algorithm with a unique objective function based on Legendre orthogonal polynomial expansion (LOPE) and genetic algorithm (GA) optimization, for determining the elastic constants of laminated composites. To implement this approach, laser vibrometry is used to acquire time-space wavefields of guided waves. The wavefields are then transformed into frequency-wavenumber spectra via multi-dimensional Fourier transform, unveiling the frequency-wavenumber relations in different directions, which are subsequently processed by our LOPE-based inversion algorithm. Particularly, this algorithm allows for robustly determining multiple elastic constants without requiring guided wave mode identification. Additionally, it is a generalized approach applicable to laminated composites with various anisotropic lamina properties and layups.
