However, there remains ambiguity regarding the suitable porous lattice structure, which significantly influences bone formation. The study aims to evaluate and compare the tissue ingrowth capability of different porous lattice structure implants on their surface using mechanoregulatory tissue differentiation algorithm. Computer-aided design (CAD) models of five topologies, namely cubic, X-shape, cubic centre, face centre, and octet, were created using Solidworks with similar porosities (60 %). Further, the study entailed the 3D microscale modelling of regular porous structured implants with five distinct repeating cells on their surface were constructed using Solidworks. Additionally, five FE microscale models of bone-implant interface were modelled, with each model representing a distinct porous lattice structure implant. Lattice tissue ingrowth behaviour is evaluated by employing a mechanobiological algorithm to every FE microscale model. The bone ingrowth efficiencies of the five porous lattice structure implants were ranked. By observing the results, it was found that each lattice structure displays distinct tissue differentiation behaviour. Results demonstrate that highest bone tissue ingrowth was seen in implant with cubic lattice followed by FCC, octet, cubic centre, and X-shape lattice structure implant. Among the five lattice structure implants analysed, the X-shape lattice structure implant promotes lowest bone tissue ingrowth.

Firstly, the role played by the hydrostatic pressure gradient at a crack tip in anodic dissolution is centralised by the proposed partial differential equation system, so as to formulate the interplay of load and corrosion in a mechanistic manner. As a result, the model can naturally reproduce the repeated film rupture mechanism that is believed central to general SCC phenomena. Secondly, the model implementation is extremely efficient, outputting a full-life SCC prediction within a few seconds on a normal laptop computer. Thirdly, a general rule for model calibration is introduced against limited experimental data, enabling its predictability over SCC indices that are not experimentally trackable. The efficacy and the generality of the proposed model are examined with three SCC scenarios, including (a) Inconel 600 alloys in nuclear pipelines, (b) stainless steels in oil pipelines, and (c) magnesium alloys used as structural materials in blood vessels.
