• The accuracy of two fatigue criteria for multiaxial random loading is discussed. Fatigue tests related to 10NHAP steel and available in the literature are simulated. lifetime crack initiation path estimated through present criteria. agreement between experimental data theoretical results satisfactory. compared with those determined three In paper, capability both estimating life predicting me...

INTRODUCTION Multiaxial failure behavior of trabecular bone is important clinically since multiaxial loads occur in vivo, and are associated with hip fractures [1, 2] and implant loosening [3]. Knowledge of the multiaxial failure behavior of trabecular bone also has biological importance since it will enable whole bone finite element models [4] to accurately predict failure loads. To date, no c...
