Finite Element Analysis

Finite Element Analysis

The requirements for light-weight design and miniaturization of modern products demand optimized material utilization. Only knowledge of the exact service loads allows for a specific and optimized design and dimensioning. In order to determine service loads, we cooperate on one hand closely with the Steinbeis Transfer Center BWF for experimental stress analysis (utilizing strain gauges), on the other hand we can simulate loads on spinal structures or implants through a validated finite element model of the lumbar spine, which incorporates the latest research knowledge.


Besides information on the force and stress of an implant, our FEA model allows the accurate simulation of the surgical intervention impact on the spinal elements, such as changes to the center of rotation (CoR), or range of motion (RoM) of the treated or adjacent segments, changes in the intradiscal pressure, facet joint forces or the bone-implant-interface load. This knowledge not only allows a load-optimized design, it really is the basis for a physiologically optimal design of an implant or prosthesis.


The reduction of development time by predicting the mechanical performance and thereby reducing the number of prototypes, design iteration loops, cost and time are key arguments for the utilization of finite element analysis.
Besides the capabilities of the software, the experience of the simulation engineer is essential for dependable results. Our engineers are experienced users and sought-after experts for FEA and in particular the design and dimensioning of medical implants.
