The strange mechanics of an elastic rod under null-resultant transverse loads
Davide Bigoni, Diego Misseroni, Andrea Piccolroaz
Two equal and opposite distributed dead loads are applied orthogonally to the axis of an elastic rod in its rectilinear reference configuration, one at the extrados and the other a…
Homogenization of architected materials incorporating shearable beams
Matteo Franzoi, Davide Bigoni, Andrea Piccolroaz
Two-dimensional architected materials are often realized as periodic grids of elastic beams. Conventional homogenization methods represent these structures as equivalent elastic so…
Material instability and subsequent restabilization from homogenization of periodic elastic lattices
Davide Bigoni, Andrea Piccolroaz
Two classes of non-linear elastic materials are derived via two-dimensional homogenization. These materials are equivalent to a periodic grid of axially-deformable and axially-prel…
Homogenization of elastic grids containing rigid elements
Luca Viviani, Davide Bigoni, Andrea Piccolroaz
The inclusion of rigid elements into elastic composites may lead to superior mechanical properties for the equivalent elastic continuum, such as, for instance, extreme auxeticity.…
