# Industrial Specification: Aluminum Profile Corner Connector

## 1. Technical Definition
Structural connector for joining aluminum extrusion profiles at right angles

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 N·m torque, 20-80°C temperature, 0-1000 N axial load**. Failure boundary: **Shear stress exceeding 120 MPa, tensile stress exceeding 180 MPa, or temperature exceeding 150°C causing aluminum alloy 6063-T5 annealing**, Mechanism: **Plastic deformation due to von Mises yield criterion exceeding material yield strength (σ_y = 145 MPa for 6063-T5 aluminum), or thermal expansion mismatch (α_Al = 23.1×10^-6/°C) creating residual stresses exceeding fatigue limit**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Galvanic corrosion between aluminum connector (E° = -1.66V) and steel fasteners (E° = -0.44V) in humid environments | 8 | Material loss at interface reducing effective cross-sectional area by &gt;15%, causing joint slippage under load | Dielectric isolation using nylon washers (ε_r = 3.5) or zinc chromate coating (thickness ≥25μm) to prevent ionic conduction |
| Stress concentration at sharp internal corners (K_t ≥ 3.0) under cyclic loading at &gt;10^5 cycles | 8 | Fatigue crack initiation at corner radii &lt;1.5mm propagating through wall thickness at Paris' law rate da/dN = C(ΔK)^m where C=1.5×10^-11, m=3.5 | Fillet radii ≥3.0mm and shot peening to induce compressive residual stresses of -200 to -300 MPa at surface |
