      abstract     = {Virus capsids and crystalline surfactant vesicles are two
                      examples of self-assembled shells in the nano- to micrometer
                      size range. Virus capsids are particularly interesting since
                      they have to sustain large internal pressures while
                      encapsulating and protecting the viral DNA. We therefore
                      study the mechanical properties of crystalline shells of
                      icosahedral symmetry on a substrate under a uniaxial applied
                      force by computer simulations. We predict the elastic
                      response for small deformations, and the buckling
                      transitions at large deformations. Both are found to depend
                      strongly on the number of elementary building blocks N (the
                      capsomers in the case of viral shells), the Föppl-von
                      Kármán number gamma (which characterizes the relative
                      importance of shear and bending elasticity), and the
                      confining geometry. In particular, we show that whereas
                      large shells are well described by continuum
                      elasticity-theory, small shells of the size of typical viral
                      capsids behave differently already for small deformations.
                      Our results are essential to extract quantitative
                      information about the elastic properties of viruses and
                      vesicles from deformation experiments.},
