โœฆ Synopsis

The effect of microcracks in a rat tibia under torsional loading was investigated using a finite element analysis. A global damage parameter (stiffness loss) and a local damage parameter (reduction in tresca stress) were used to estimate the severity of the damage due to circumferential and radial type micrccracks. 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 finite element simulation of microdamage in a bone tissue.
