Wellcome to FEA WORKS! 


On the one hand, you receive services for the application of the Finite Element Method (FEM) in all areas of development, research and industry.

We work on engineering problems for you from the fields of statics , dynamics , thermodynamics and fluid mechanics . FEM calculations, proof of strength , lifetime proof , proof of screws , rivets and welds as well as component optimization and CFD analyzes are our daily business.



Stent designs and stent FEA

On the other hand, you get finished stent designs or stent models for download free of charge.These models are tested and designed according to standard and may be further processed.

We creatively develop stent models and medical implants and provide you with this stent models database free of charge. You may download our models and process them for your own purposes. If you want to know more about the subject, feel free to contact us.

The following international standards and regulations serve as a basis for stent designs and the corresponding proofs and fatigue tests :


ISO 25539-1: Cardiovascular implants – Endovascular devices – Part 1: Endovascular prostheses

ISO 25539-2: Cardiovascular implants – Endovascular devices – Part 2: Vascular stents

ISO 25539-3: Cardiovascular implants – Endovascular devices – Part 3: Vena cava filters

ASTM F2514: Finite Element Analysis (FEA) of Metallic Vascular Stents Subjected to Uniform Radial Loading

ASTM F2477: Standard Test Methods for in vitro Pulsatile Durability Testing of Vascular Stents

ASTM F2942: Standard Guide for in vitro Axial, Bending, and Torsional Durability Testing of Vascular Stents
