Simulation of mechanical behavior of calcium-phosphate coatings with different calcium content under shear loading based on the movable cellular automaton method

The discrete movable cellular automaton method (MCA-method) is used to develop a technique for determining shear components of the stress and strain tensor in an arbitrary elementary volume of the specimen. We perform calculations for different calcium distributions through the coating thickness, which correspond to different methods of calcium distribution or different time of its being in the organism. The calculation results allow us to evaluate elastic properties as well as shear strains and stresses depending on the distribution of elements in the coating. For the chosen coating compositions we determine calcium distributions at which the shear stress and strain values in the coating are maximum and minimum.
