Four simplified gradient elasticity models for the simulation of dispersive wave propagation
, 2008 Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model
, 2004 The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models that involve gradients of the strain field means that the $C^0$ continuity

A method for creating a class of triangular C1 finite elements
, 2011 Finite elements providing a C1 continuous interpolation are useful in the numerical solution of problems where the underlying partial differential equation is of fourth order, such as beam and plate bending and deformation of strain-gradient-dependent ...

Uniqueness for plane crack problems in dipolar gradient elasticity and in couple-stress elasticity
, 2005 The present work deals with the uniqueness theorem for plane crack problems in solids characterized by dipolar gradient elasticity. The theory of gradient elasticity derives from considerations of microstructure in elastic continua [Mindlin, R.D., 1964 ...
