Description
Subtract installedThickness from positive freeThickness and divide by freeThickness for compressionFraction; multiply by 100 for compressionPercent.
A simple strain, compression, or neutral-axis formula models only part of a material's behavior. Geometry, loading, elasticity, and fatigue assumptions govern how the result can be used.
Subtract installedThickness from positive freeThickness and divide by freeThickness for compressionFraction; multiply by 100 for compressionPercent.
When to use this tool
Use Enclosure Gasket Compression Percentage Term when you need one explicit deformation-model component.
How to use the tool and how it works
- Enter freeThickness, installedThickness. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read compressionFraction, compressionPercent. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| freeThickness | Free Thickness | Required. Finite number; strictly above 0. |
| installedThickness | Installed Thickness | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| compressionFraction | Fractional thickness reduction; negative for expansion. | Required. Finite number. |
| compressionPercent | Thickness reduction multiplied by 100 for percent. | Required. Finite number. |

}Limitations and assumptions
- An installed thickness larger than free thickness gives negative compression; sealing, material recovery, and safe compression limits are not assessed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use validated material data and an appropriate mechanical analysis and test for safe design decisions.
