# Industrial Specification: Pressure Plate Assembly

## 1. Technical Definition
A mechanical assembly that applies controlled pressure during sole attachment operations

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-80 bar**. Failure boundary: **95 bar (yield strength of AISI 4140 steel at 250°C)**, Mechanism: **Plastic deformation due to exceeding yield strength (σ_y = 620 MPa at 20°C, reduces to 480 MPa at 250°C) under cyclic loading, leading to permanent dimensional changes and loss of pressure uniformity**.

### 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.

| Symbol | Variable Definition | Localized Reference |
