In the end, Alex learned a valuable lesson about the importance of using legitimate software and the potential risks associated with cracked versions. The project was completed successfully, and the client was satisfied with the results.
| # | Requirement | Description | Acceptance Criteria | |---|-------------|-------------|---------------------| | | Stress Capture | Leverage the existing dynamics engine to export per‑frame stress tensors for every rigid body and mesh node. | Stress data available for all bodies at ≥ 30 Hz during simulation. | | FR‑2 | Material Database | Extend the material library with fracture‑mechanics parameters (K_IC, fatigue exponent, etc.) for common alloys (Al‑6061, 304 SS, carbon steel, composites). | User can assign a material to any part; the database contains at least 12 pre‑populated entries. | | FR‑3 | Crack‑Risk Algorithm | Implement a real‑time heuristic: 1. Compute von Mises stress at each node. 2. Compare against material’s endurance limit. 3. Estimate crack‑initiation probability using a Weibull‑type function. 4. Propagate an “virtual crack” using a simplified Paris‑law step. | When a simulated load exceeds 80 % of the material limit, a red overlay appears within 0.2 s. | | FR‑4 | Visualization Overlay | Add a toggleable overlay layer in the 3‑D view. Colours: • Green – < 50 % risk • Yellow – 50‑80 % risk • Red – > 80 % risk Overlay updates every simulation frame. | User can enable/disable overlay; colours match risk thresholds; overlay does not degrade frame‑rate below 20 fps on a mid‑range GPU. | | FR‑5 | Report Generation | Export a comprehensive crack‑analysis report with: • Part name & material • Location (XYZ) and surface normal • Estimated crack length & growth rate • Suggested mitigation actions • Simulation screenshots. | Clicking Generate Report creates a PDF/HTML file ≤ 5 MB, containing all identified cracks. | | FR‑6 | What‑If Simulation | Allow the user to manually insert a virtual crack (size, orientation) on any surface and re‑run the simulation to see performance impact. | User can add a crack up to 5 mm; after insertion, the simulation updates stress fields and overlays instantly. | | FR‑7 | API Exposure | Provide a Python/JavaScript API ( roboguide.crackBetter.* ) for custom scripts (e.g., automated batch analysis). | Sample script demonstrates loading a project, running analysis, and exporting the report. | | FR‑8 | Backward Compatibility | Feature can be disabled without affecting existing projects. | Turning off “Crack‑Better” leaves all other functionalities untouched. | fanuc roboguide v640 rev e crack better
