Abstract: Compressing viscoelasticity of cancellous femur upper part of normal fresh corpse of our country was studied experimentally including compressing stress relaxation and creep test in 3 directions:longtitudinal,transversal,and in 45癲irection.Normalized stress relaxation and creep functions were regressed from obtained data and illustrated in curves.Results showed both longtitudinal stress relaxation and creep of cancellous femur upper part are larger than those in other 2 directions,demonstrating it is an anisotropic material.

Key words: cancellous femur upper part, viscoelasticity, anisotropy
