In this work the solution of the structural problem obtained by mean of the velocity approach is presented. More in detail the balance and constitutive equations are expressed in Eulerian form, the mesh is not material. The approach is general, is suitable both for material boundary or no-material boundary and for a generic material model. The Hooke's elastic model and the Anand's plasticity model are considered. Some 2D and 3D cases are developed to study and verify this approach with respect to the structural problem.
