Ceramic Total Hip Liner Fracture Modeling in Abaqus using co-Simulation and Extended Finite Element Modeling
Due to concerns over particle generation in conventional metal-on-polyethylene hip bearings used in total hip arthroplasty (THA), interest in advanced low-wear bearing alternatives such as ceramic-on-ceramic (CoC) couples has reemerged. While ceramics demonstrate excellent compressive strength, the brittle nature of the material reduces tensile strength, possibly leading to catastrophic fractur...
متن کاملPatient Specific Finite Element Modeling of Lumbar Vertebrae
It is the purpose of this work to investigate whether it is feasible to develop Finite Element (FE) models that take into account the geometric differences between the lumbar vertebrae of patients. It is also the purpose of this work to determine whether or not such patient specific differences affect the results of the FE analysis in such a significant way that they should be considered in fut...
متن کاملAssessment of Hip Fracture Risk Using Cross-Section Strain Energy Determined by QCT-Based Finite Element Modeling
Accurate assessment of hip fracture risk is very important to prevent hip fracture and to monitor the effect of a treatment. A subject-specific QCT-based finite element model was constructed to assess hip fracture risk at the critical locations of femur during the single-leg stance and the sideways fall. The aim of this study was to improve the prediction of hip fracture risk by introducing a n...

متن کاملFinite Element Modeling of Crack Initiation Angle Under Mixed Mode (I/II) Fracture
Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...
