Keywords: | titanium alloys orthopaedic prosthesis mechanical behaviour dynamic mechanical analysis porous coating |
Abstract (eng): | The project deals with titanium and titanium alloys as biomaterials for implants applications, focusing on their mechanical response under dynamic stresses occurring during common human activities. In the first part, the biomaterials requirements for orthopaedic implants, the properties and the processing of titanium alloys are described. From the combined biomechanics requirements, mechanical behaviour of the materials and the bone is analysed and the additional poroelastic behaviour is added for fluidic transport inside porous material undergoing oscillatory mechanical deformation. Based on these analyses, the biomechanical behaviour of titanium alloy for orthopaedic prosthesis is simulated by finite elements analysis with the software COMSOL Multiphysics. The simulations concern dynamic mechanical three-point bending coated specimens, studying the influence of porous coatings with different characteristics of thickness and porosity. Experimental tests with dynamic mechanical analysis (DMA) are performed in order to validate the model. |
