Distinguishing modes of time-resolved fibrillar mechanics and the response of chitin fibres to compressive load (vertical arrows). Chitin fibres oriented initially along the loading axis [(a1) original fibril array, (a3) original fibres in the tissue] may broaden the in-plane distribution [(a1)→(b1), (a3)→(b3)] or tilt as a block out of the plane [(a1)→(c1), (a3)→(c3)]. The X-ray diffraction patterns (and azimuthal plots) would show a similar broadening effect in both cases [(a2)→(b2), (a2)→(c2)] although at different rates. (d) FWHMs of the (110) reflection at the two conditions at a given wμ. The orange plot shows the increase in the in-plane fibril distribution (Δγ0) and the blue plot shows the increase in the fibril tilt (α).
