Description

For orthopaedic device designers, the Human Biological Materials module is a unique resource of mechanical property data for specific bones, enabling fast access to data suitable for FEA and general reference. It is fully linked to original data sources for further investigation if required.

This first release concentrates on the properties of the primary load bearing bones—femur, tibia, acetabulum and vertebrae. Future releases will add data on other bones and tissues.

The data is acessible within the GRANTA MI materials information system, providing easy web browser-based access (pictured, above). Searching or browsing is simple and intuitive, allowing designers to quickly find the information that they need. Data can be viewed, queried, and applied as numbers, text, or graph and functional data (of particular value in representing complex mechanical properties).

Other medical data modules available in GRANTA MI include information on the materials used in orthopaedic and cardiovascular devices. All of this information can be accessed in the same environment, creating a single integrated source for data on biological and materials data. This saves time in data searches and facilitates the comparison of materials.

Once you have found the data that you need, properties can be exported in the standard formats required by a range of FEA packages, enabling its immediate use in simulation.

What data is included?

The first release includes tensile, compressive, flexural and general properties of the femur, tibia, vertebrae and acetabulum with age and direction dependence.

Full reference sources are provided as part of the data set.

Regular releases will enhance and update the data.

With the Human Biological Materials data module you can:

• Understand the effects of patient age on your device design
• Support simulation with accurate property data from a traceable source
• Ensure that consistent data is used across your design team
• Access the data that you need within your familiar browser—there is no need to install software on your PC
• Compare with in-house data and data from other sources, all within a single environment
