# Industrial Specification: Actuator Body

## 1. Technical Definition
The main structural housing of an edge actuator that contains and protects internal components while providing mounting interfaces.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-250 bar hydraulic pressure, -40°C to +120°C ambient temperature**. Failure boundary: **Material yield strength threshold at 350 MPa for aluminum alloy 6061-T6, 450 MPa for steel AISI 4140**, Mechanism: **High-cycle fatigue failure due to cyclic pressure loading exceeding 10^7 cycles at 80% of yield strength, following Basquin's law σ_a = σ_f' * (2N_f)^b where σ_f' = 900 MPa and b = -0.12 for typical actuator materials**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
