The far-field response of a bi-axially pre-stressed incompressible elastic plate, subjected to an instantaneous edge impulse loading, is studied using a refined long-wave low-frequency theory. The second-order correction introduced by the refined theory is demonstrated to smooth the discontinuity...
I report on a contribution to the point symmetry classification problem for second-order partial differential equations (PDEs) in z ( x , y ), i.e. to an overview over all possible symmetry groups admitted by this class of equations. The article also contains a concise introduction into classical...
