Finite Element Analysis

We simulate loading scenarios using finite element analysis (FEA) to predict medical device performance

We develop finite element models to create virtual simulations of your orthopaedic implant under real-life loading conditions. FEA is beneficial to predict short- and long-term device performance and durability, and to identify worst-case-scenario loading and implant configurations quickly and effectively. Finite element modeling allows the opportunity to combine and apply complex physiological loading with intricate designs to evaluate and improve product development without limits. Choosing FEA provides a strong forefront to mechanical testing to ensure appropriate test methods are applied.

We follow standardized FEA methods and create custom simulations tailored to your orthopaedic medical device and clinical loading conditions. Our FEA simulation methods are designed to determine best and worst-case scenarios, evaluate device performance, and pin-point failure modes.

Our FEA engineering team is active in ASTM and ISO arthroplasty standards committees to ensure the latest industry best-practices are applied to your analyses. If a non-standard method is needed, we will develop and incorporate modifications to suit your specific device and data needs.

Having a strong foundation in clinical research provides you with the additional value of a clinically-relevant simulation. We pride ourselves on the ability to meet a customer’s specific needs with a wholly unique, tailored solution.

Standard Practice for Finite Element Analysis (FEA) of Non-Modular Metallic Orthopaedic Hip Femoral Stems
Describes standardized methods for finite element analysis (FEA) to estimate the stresses and strains on non-modular metallic orthopaedic hip stems. This standard practice is used to assess and identify worst-case scenarios within a family of implant sizes, and to provide guidance for physical testing. The procedures of this FEA standard follow the mechanical methods outlined in ISO 7206-4.
Standard Test Method for Finite Element Analysis (FEA) of Metallic Orthopaedic Total Knee Femoral Components under Closing Conditions
Describes standardized test methods for finite element analysis (FEA) for estimating the static stresses and strains on total knee femoral components. This test method is applied to assess and identify worst-case scenarios within a family of implant sizes, and to provide guidance for physical testing, device design, material selection, and manufacturing variables.
Standard Practice for Finite Element Analysis (FEA) of Metallic Orthopaedic Total Knee Tibial Components
Describes standardized methods for finite element analysis (FEA) to estimate the static stresses and strains on metallic orthopaedic total knee tibial components. This standard practice is used to evaluate for worst-case within a series of different implant sizes of the same implant design. The finite element models developed follow ASTM F1800 practice for cyclic fatigue testing of metal tibial tray components.
FEA for Orthopaedic Devices
We design custom FEA models specific to your orthopaedic implants such as spine, shoulder, ankle, hip, knee, and wrist devices, and corresponding physiological loading conditions. Our medical device testing services support validation of these methods to provide accurate results.
