註釋

Each of the two 38 X 38-cm square panels, consisting of 28 plies of plain-woven 600-denier Kevlar KM2 and a Cordura case, was loaded in quasistatic, transverse compression by means of an Instron machine. Constitutive assumptions were introduced to allow for calculation of Green-St. Venant strain, second Piola-Kirchhoff stress, and Cauchy stress. A least squares fit in the form of a rational function was obtained for each second Piola-Kirchhoff stress vs. Green-St. Venant strain curve.
