MECHANICAL PROPERTY EVALUATION OF POLYMERIC BIOMATERIALS VIA FINITE ELEMENT SIMULATION METHOD

摘要：

Polymer-based biomaterials may be a good candidate for replace soft tissue, because synthetic polymers that have various properties can be produced by changing the amount or kind of reactant and used according to its purpose. Polymer-based biomaterial has been prepared from PLGA, dioxane and tricalcium phosphate (TCP), by low-temperature deposition process. Mechanical properties of the prepared biomaterials were tested using compression experiment. The results show that the disperse distribution of TCP can affect the mechanical property of polymer-based biomaterials. Then, the flow stress regression models were built to evaluate the mechanical property of these biomaterials according to difference of the yield rule. The fracture behaviors of polymeric based biomaterials during deformation process were investigated using the finite element simulation. The fracture mechanism can be considered as brittle fracture.
