Material Library: High-Fidelity Physical Properties Data
At Edelweis, we recognize that a simulation is only as accurate as the material data driving it. We reject the use of generic placeholders. Our Centralized Material Library (CML) provides a synchronized database of high-fidelity physical properties, ensuring that every CAD model carries the precise mechanical "DNA" required for advanced CAE & Validation.
1. The Edelweis Material Standard
Every material entry in our library is verified against international standards (ASTM, ISO, DIN) and supplier data sheets to eliminate discrepancies:
-
•
Mechanical Isotropics: Beyond standard density, we define Poisson’s Ratio, Shear Modulus, and Yield/Tensile strengths for specific manufacturing tempers (e.g., T6 for Aluminum).
-
•
Thermal Dynamics: Accurate Thermal Expansion Coefficients, Conductivity, and Specific Heat are embedded to support complex CFD and Heat Transfer studies.
-
•
Non-Linearity & Hyperelastics: For polymers and elastomers, we incorporate Stress-Strain tables to allow for accurate FEA under large deformation.
2. Manufacturing-Specific Metadata
| Property Type | Data Point | Engineering Utility |
|---|---|---|
| Physical | Density (ρ) | Real-time Mass and Center of Gravity (CoG) calculation. |
| Structural | Fatigue Strength | Predicting lifecycle and failure points under cyclic loading. |
| Process | Machinability Rating | Estimating CNC cycle times and tool wear costs. |
| Regulatory | RoHS / REACH | Ensuring global environmental and safety standard adherence. |
| Supply Chain | Unified Material ID | Mapping CAD data directly to your ERP/MRP sourcing database. |
3. Surface Finish & Texture Mapping
-
•
Anisotropic Reflections: Brushed or machined surfaces mapped with realistic light-scattering properties for high-end rendering.
-
•
Coating Simulation: Accounting for the physical volume and mass of surface treatments (powder coating, anodizing) in precision assemblies.
-
•
Color Matching: Appearances locked to RAL/PANTONE standards to ensure visual fidelity during stakeholder reviews.
4. Custom Material Characterization
For partners using proprietary alloys or composites, we offer specialized characterization services:
Test Data Ingestion
Converting physical lab test data (Tensile, Hardness) into digital files compatible with SolidWorks solvers.
Anisotropic Mapping
Defining directional stiffness for composites based on specific ply-stacking sequences.
Technical Directives
| Directive | Protocol |
|---|---|
| No "Generic" Materials | Use of default placeholders is flagged by our Model Quality Check (MQC). |
| Library Sync | Engineers must use the EDL_Global_Mat_Lib for consistency across sub-assemblies. |
| Validation Lock | Material properties are "frozen" during the Pending Review phase to prevent data mismatch. |
