High Speed Testing of Medical Devices and Materials
An important input to FEA is material characterization and limit information. In our laboratory we use a Bose 3230 test system for achieving test [...]
Identifying Worst Case Device Sizes
For medical devices, rarely does "one size fit all". The human body is extremely variable and patient populations, especially those with disease present a [...]
Interpreting FEA Results: Integration Point Data
Finite Element Analysis (FEA) can produce an enormous amount of data as output. Solution variables such as stress and strain are computed throughout an [...]
FEA Geometry and Edge Detail
A typical process for making stents is electropolishing to remove material and processing defects and to impart a smooth finish with rounded corners. It [...]
The Selection of Nitinol Material Models for FEA Simulations
Nitinol is a unique metallic alloy that is ideally suited to use in medical devices. It has excellent biocompatibility and most of all it [...]
Medical Implant Material Fatigue Research
With the growing use of Nitinol in medical implants, there is a need for improved characterization of the material behavior of Nitinol and methodologies [...]
