      Stress intensity factor computation using the method of fundamental solutions: Mixed-mode problems 

      Berger, J. R.; Karageorghis, Andreas; Martin, P. A. (2007)
      The method of fundamental solutions is applied to the computation of stress intensity factors in linear elastic fracture mechanics. The displacements are approximated by linear combinations of the fundamental solutions of ...

      A survey of applications of the MFS to inverse problems 

      Karageorghis, Andreas; Lesnic, D.; Marin, L. (2011)
      The method of fundamental solutions (MFS) is a relatively new method for the numerical solution of boundary value problems and initial/boundary value problems governed by certain partial differential equations. The ease ...

      Viscoplastic flow in an extrusion damper 

      Syrakos, A.; Dimakopoulos, Yannis; Georgiou, Georgios C.; Tsamopoulos, J. (2016)
      Numerical simulations of the flow in an extrusion damper are performed using a finite volume method. The damper is assumed to consist of a shaft, with or without a spherical bulge, oscillating axially in a containing ...

      Viscoplastic Poiseuille flow in a rectangular duct with wall slip 

      Damianou, Y.; Georgiou, Georgios C. (2014)
      We solve numerically the Poiseuille flow of a Herschel-Bulkley fluid in a duct of rectangular cross section under the assumption that slip occurs along the wall following a slip law involving a non-zero slip yield stress. ...
