Results of tensile deformation. (a) Stress–strain curves of α-synuclein, three Aβ₄₀ and two Aβ₄₂ fibrils. Circles correspond to v = 0.0005 Å/τ. The error bars are the same as the symbol size and they are based on 50 independent simulations for each structure. The insets show the corresponding cross-section areas in nm² for the corresponding pulling speed. (b) Distributions of HB lengths for (solid lines) and for a finite strain corresponding to the end of the linear regime (dashed lines): for α-syn the final , while for Aβ amyloids.
