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 [...]
FEA of NIKE AIR
My first job out of graduate school and post-doctorate work was with the footwear company, NIKE. I was fortunate to hire into the health [...]
Contact Interaction for Medical Implants
There are many circumstances when it is necessary to model contact and contact interactions when analyzing medical implants. Such circumstances arise when devices interact [...]
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 [...]
Evaluating Design Instabilities with FEA
Finite Element Analysis is routinely used to evaluate the performance and durability of medical devices. When using an implicit method such as ABAQUS/Standard, FEA [...]
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 [...]
