As part of the characterization of plant fibers, considering the non-uniformity of the cross section along the fiber, what should be considered to calculate the breaking stress? the middle section resulting from several measurements? weakest section? or using the variation of the deformation energy?
Given the difficulty of obtaining the actual cross-section of the plant fiber due to the variability of its cross-section. It is recommended to take the average cross-section ( 05 minimum positions) of each unit fiber.
In my opinion, this is closer to reality, given the results of numerical simulations using software.
Hello,
there are several methods for calculating the effective cross-section, and this measurement also depends on the method used to measure the diameter.
With SEM, one method is to take the cross-sectional contour of the fiber close to the fracture zone, to minimize dispersion. I invite you to take a look at Marie Gregoire's article, which gives a good overview of these different methods and their advantages and limitations.
Happy reading!
