Analysis of stress field in Al2O3-ZrO2 biomaterials by finite element method

ABSTRACTWe present an investigation of the mechanical properties of Al2O3-ZrO2 as duplex-structured materials using the finite element method (FEM). The creation of stress fields are a result of the material trying to dissipate mechanical energy that is being exerted on the biomaterial. By finite element modelling and the stress fields, as either compressive or tensile, we can understand how inclusions interact with each other bioceramic lattice containing alumina in the presence of different zirconia contents. The stress fields can be applied to various strengthening mechanisms in bioceramic. They can be created by adding several inclusions in alumina lattice.
