New Test Method for Standard Test Method for Four-point Bend Testing of Metallic Bone Plates using the Finite Element Method
1. Scope
1.1 This standard establishes requirements and considerations for the numerical simulation of metallic orthopaedic bone plates per ASTM F382 using Finite Element Analysis (FEA) techniques.
1.1.1 Question of Interest
1.1.1.1 This test method describes methods for single cycle bend analysis (four-point bending) per ASTM F382 Annex A1 using the finite element method to determine the intrinsic, structural properties of metallic bone plates: bending stiffness, bending structural stiffness, and bending strength of bone plates to allow for comparisons between plate designs.
1.1.1.2 This test method describes methods for bend analysis (four-point bending) per ASTM F382 Annex A2 using the finite element method to predict implant stresses and strains and to allow for comparisons between plate designs.
1.1.2 Context of Use
1.1.2.1 The test method may be used to determine “worst case” sizing analysis for static and fatigue evaluation of bone plates under four-point bending.
1.1.2.2 The test method may be used to in lieu of physical testing to determine static and fatigue properties of bone plates.
Keywords
Bone plate, finite element analyses
Rationale
Current physical test methods for testing metallic bone plates are described in ASTM F382. This document will describe corresponding analytical methods (finite element analyses).
The title and scope are in draft form and are under development within this ASTM Committee.
