    • A new damage model based on non-local displacements 

      Rodríguez Ferran, Antonio; Morata, I; Huerta, Antonio (2005-04)
      Article
      Accés obert
      A new non-local damage model is presented. Non-locality (of integral or gradient type) is incorporated into the model by means of non-local displacements. This contrasts with existing damage models, where a non-local strain ...
