Material library
01Overview
Typical composite, core and metal properties. All with clear source designation or measured in our own laboratory.
A blade simulation is only as reliable as its material data. econblades gives you measured or validated typical values from the start, so you don't define materials from zero or rely on datasheets collected from the web.
02What it does
Materials in one place.
The library holds typical composite and metal materials, including core materials such as PVC foam and honeycomb.
Measured materials.
Many of the material datasets are based on tests in eCon's material laboratory. For each one, the material description records which tests the values come from.
Fatigue data included.
Fatigue parameters use fitted Haigh-diagram parameters from in-house experiments and enable fatigue analysis in econblades.
Properties for blade integrity.
For several materials, the special strength properties needed for integrity and fatigue checks are already in the database.
Testing on demand.
If a material or property is missing, our composite testing lab measures it for you.
03Classical way vs. econblades
Classically, material data comes from supplier datasheets or from characterisation tests that cost time and budget before the first simulation runs. At the preliminary stage, the econblades library replaces most of these tests. Entering a material takes the same effort in any tool. The difference is where the numbers come from.
04Inputs and outputs
Materials feed the Layup builder, where you assign them to plies. The same data drives the strength, vibration, deformation and fatigue analyses in Calculation and report.
05Scope
The library grows over time and doesn't cover every material. When yours is missing, we can measure it.
06FAQ
Where does the material data come from?
From either open source databases or in-house mechanical tests in eCon's own material laboratory. Each entry notes the tests its values are based on.
Can I add my own materials?
Yes. You can add materials from datasheet values or your own test data. econblades uses them as entered.
What if the material I need isn't in the library?
Contact us. Our composite testing lab can run the tests and add the parameters you need.
How do I know which material model and strength assessment approach suits my blade?
econblades comes with a detailed ‘Theory Guide’ that explains every material constitutive model and strength model, including fatigue. If you're still unsure, feel free to ask us for advice.
