description: Additional file 1: The simulation model construction and the results of the mechanical response in each model when the elastin content was set to 10.1% are summarized. Fig. S1. Differences in stress distribution between sheet and fibre models with 10.1% elastin. a Stress distribution in the sheet model (left) and the fibre model (right) under tensile stress. XZ-plane (top), XY-plane (medium), and cross-section in the YZ-plane at the dotted line in the centre of the model (bottom) are shown, respectively. Black arrow indicates the direction in which tensile stress was applied. b Summarized data of average and maximum stress in the sheet model (white boxes) and the fibre model (black boxes) under tensile stress. c Stress distribution in the sheet model (left) and the fibre model (right) under shear stress. XZ-plane (top), XY-plane (medium), and cross-section in the YZ-plane at the dotted line in the center of the model (bottom) are shown, respectively. Black arrow indicates the direction in which shear stress was applied. d Summarized data of average and maximum stress in the sheet model (white boxes) and the fibre model (black boxes) under shear stress. e Stress distribution in the sheet model (left) and the fibre model (right) when the bone was rotated by 30°. XZ-plane (top), XY-plane (medium), and cross-section in the YZ-plane at the dotted line in the centre of the model (bottom) are shown, respectively. f Summarized data of average and maximum stress in the sheet model (white boxes) and the fibre model (black boxes) when the bone was rotated by 30°. g Stress in Y and Z directions required to rotate the bone by 30° in the sheet model (white boxes) and the fibre models (black boxes). Fig. S2. Difference in stress distribution in the fibre model in the absence and the presence of 10.1% elastin. a Difference in stress distribution between the models in the absence (Left) and the presence (Right) of elastin under tensile stress. b Differences in stress distribution between the models in the absence (Left) and the presence (Right) of elastin under shear stress. c Differences in stress distribution between the models in the absence (Left) and the presence (Right) of elastin when the bone was rotated by 30°. In each panel, the upper surface of the collagen fibers on the third raw are shown at the bottom.
