as expected. Furthermore the 2D simulation of a
femur under distributed pressure gave reasonable
results. The numerical results are very promising
about the potentiality of the method for the crea-
tion of 3D models from CT-scans which will enable
us to assign properties rigorously and to get closer
to the real behaviour of human tissues.
