Development of Surrogate Model for Patient-Specific Lattice-Structured Hip Implant Design via Finite Element Analysis

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(7), P. 3522 - 3522

Published: March 24, 2025

Patient-tailored hip implants are a major area of development in orthopedic surgery. Thanks to the recent developments titanium printing, medical industry now places special demands on implants. The lattice design enhances osseointegration and brings stiffness implant closer that bone, so this is an important direction processes. In our previous research, several structures were compared from strength perspective, considering surgical specifications regarding cell size. so-called 3D infill type built into ANSYS with predefined size has proven be suitable for practice can easily manufactured additive manufacturing techniques. A step process numerical analysis, which elucidates material response. Due complex geometry structure, finite element calculations extremely time-consuming require high computation capacity; therefore, focus current research was develop surrogate model provides sufficiently fast accurate information about behavior designed structure. developed reduces simulation time by more than one hundred times, accuracy calculation satisfactory engineering practice. deviation original is, average, below 5%, taking deformation account. This makes phase much manageable competitive.

Purpose This study examines the accuracy of a homogenization scheme for linear buckling analysis structures assembled from beam-based lattice plates. Regardless in-plane acting loads, behavior is characterized by abrupt out-of-plane deformation. Apparently, if plates are modeled as homogenized ones, effective material properties should be considered. However, prevalently implemented in literature, assigned to analysis, and thus, results erroneous. Design/methodology/approach The performed two finite element models, i.e. high- low-fidelity models. In former one, each strut an Euler–Bernoulli beam, all geometrical features explicitly simulated. On other hand, one involves having determined counterparts using energy-based method. Findings confirmed comparison obtained Six topological configurations unit cells considered, first five modes inspected. examinations, model offers acceptable level accuracy, relative difference between models lower than 5%. Furthermore, it recommended use rather ones ensure precise simulation. Originality/value current original. there some studies regarding or panels with properties. these analytical approach, consequently, they confined whose geometry simple. present paper, examined. It can noticed that have complex geometry. Therefore, feasibility validated.
