Fig 3. Stress distribution on CCMV shell surface.

Map of the Cauchy stress tensor projections along the direction of out-of-plane bending deformation (left) and tangential in-plane stretching (right) for different deformation X of the CCMV shell and corresponding indentation force F (indentation along the 2-fold symmetry axis with R _tip = 20 nm and ν _f = 1.0 μm/s). For each amino acid residue (C _α-particle), the stress components are averaged over amino acids within a sphere of radius R _C = 15 Å (color denotation is presented in the graph). Also shown are formation and subsequent evolution of microscopic cracks in the side portion (particle barrel) of CCMV structure (shown in red circle/ellipse).
