“…The presented analytical model is used to identify an apparent transverse elastic modulus 𝐸 𝑇 𝑎𝑝𝑝 from FEA data through a least-squares regression analysis as detailed in [44]. The relative difference between the apparent fiber transverse elastic modulus, 𝐸 𝑇 𝑎𝑝𝑝 , identified by the analytical model, and transverse elastic modulus defined in the FEM, 𝐸 𝑇 , is calculated:…”

“…For all the fibers studied, the fiber's longitudinal modulus is set at 𝐸 𝐿 = 50 𝐺𝑃𝑎, which is in the order of magnitude of common bast fibers such as flax, hemp and nettle [6,46]. The transverse elastic modulus is set at 𝐸 𝑇 = 1 𝐺𝑃𝑎 according to preliminary experimental SFTCTs [47]. Poisson ratios have been shown to have very little influence on fiber behavior under SFTCT and subsequent 𝐸 𝑇 identification [23,44].…”

“…The transverse elastic modulus is set at 𝐸 𝑇 = 1 𝐺𝑃𝑎 according to preliminary experimental SFTCTs [47]. Poisson ratios have been shown to have very little influence on fiber behavior under SFTCT and subsequent 𝐸 𝑇 identification [23,44]. Values are thus set arbitrarily at 𝜈 𝐿𝑇 = 0.4 and 𝜈 𝑇𝑇 = 0.07.…”
