The continuum-level characterisation of how the particles within one particular group of interest mechanically influence each other under external mechanical stimuli. The evolutions of the surface-averaged internal stresses with the axial strains at a wide range of engineering strain rates (~106–1010 s −1) are illustrated for the chosen flexible cellular membrane complexes: the central group PM of the pure POPC bilayer membrane and the TM domain of integrin αIIbβ3 embedded in a patch of hydrated lipid bilayer.
