Abstract

Temperature variations can have significant effects on guide wave propagation, and therefore can increase the detection uncertainty of the structural health monitoring (SHM) system. The effect of this variation has been investigated for detecting impact damage in carbon fiber reinforced composites. Surface instrumented piezoelectric wafers are used in this work to detect the low velocity impact damage in a braided carbon fiber reinforced composite plate over a temperature range of 0 ⁰C to 60 ⁰C. The effects of temperature variation and thermal cycles on guided wave propagations in healthy composite plates are characterized first. The information is then used to develop a compensation algorithm to minimize the thermal effects on detection. A statistical damage detection and quantification approach is developed using and Auto-Regressive with eXogenous (ARX) model and local outlier analysis. The developed methodology is experimentally validated using the pitch-catch guided wave testing approach within the temperature range.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
