From: High-sensitivity strain sensor based on in-fiber rectangular air bubble
Numerical simulation for the stress concentration and the cavity length change of the four air bubble samples under an applied tensile strain.
(a) Calculated stress at the ‘A’ point on the outside surface of each air bubble versus the applied strain, (
) S1, (
) S2, (
) S3 and (
) S4; (b) Calculated cavity length change of each air bubble versus the applied strain, (
) S1, (
) S2, (
) S3 and (
)S4.
