A new approach to the stability problem of plates subjected to arbitrary complex loading

Vietnam Journal of Mechanics, 1992
The pre-buckling and post-buckling deformation processes are assumed to be less complicated, i.e. processes of average curvature, the influence of complex loading on the stability of plates was analyzed in [1]. In this paper eliminating this restriction,

Post-buckling behaviour of a growing elastic rod [PDF]

Journal of Mathematical Biology, 2018
We consider mechanically-induced pattern formation within the framework of a growing, planar, elastic rod attached to an elastic foundation. Through a combination of weakly nonlinear analysis and numerical methods, we identify how the shape and type of buckling (super- or subcritical) depend on material parameters, and a complex phase-space of ...
