Abstract
The effect of microcracks in a rat tibia under torsional loading was i nvestigated using a finite element analysis. A global damage parameter (stiffness loss) and a local damage parameter (reduction in tresca st ress) were used to estimate the severity of the damage due to circumfe rential and radial type microcracks. Results show the varying amounts of damage caused by isotropic and transversely isotropic properties of both types of microcracks. The present damage model can be used for f inite element simulation of microdamage in a bone tissue. Copyright (C ) 1996 Elsevier Science Ltd.
