Using a radial point interpolation meshless method and the finite element method for application of a bio-inspired remodelling algorithm in the design of optimized bone scaffold

The design of bone scaffold involves the analysis stress shielding, which can occur when Young’s modulus implant is higher than it replacing, leading to decay in surrounding tissue. It therefore very important that material adequately designed match properties tissue, allowing an appropriate load transfer. While some approaches exist literature exploring functional gradients density, there are much less solutions based on biological laws. A homogenized model gyroid infill obtained with PLA ( $$E = 3145$$ MPa) was through mechanical tests 3D printed specimens, namely tensile and compression, implemented a remodelling algorithm. law compared results tissue assess equivalence density distribution properties. Through radial point interpolation method, found similar fields were for subject same boundary conditions. finite element method also used comparison validation. With field results, behaviour extrapolated other materials, stiffness values titanium alloy 110$$ GPa) scaffold, justify this proposal scaffolds mimicking
