# Industrial Specification: Die Body/Housing

## 1. Technical Definition
The main structural component of a die head that houses and supports all internal die components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 MPa compressive stress, -40°C to 250°C temperature**. Failure boundary: **Yield strength threshold: 310 MPa (AISI 4140 steel), 0.5 mm permanent deformation, 300°C thermal limit for dimensional stability**, Mechanism: **Plastic deformation from exceeding yield strength (Hooke's Law: σ = Eε), thermal expansion mismatch (α = 11.7×10⁻⁶/°C for steel) causing stress concentration at bolt interfaces**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
