Summary of Main Results (image) Queen Mary University of London Share Print E-Mail Caption (a) Staggered fibrillar configuration and damageable mode II interface are responsible for hysteretic stress strain curve and heterogeneous fibrillar deformation. (b) The inclusion of staggered configuration and undamageable interface leads to hysteresis and homogeneous fibril deformation. (c) Aligned fibrillar configuration and no interface lead to no hysteresis and homogeneous fibril deformation.
