Result Interpretation

Offset Press Blanket Compression Set Depth Calculator computes Compression set depth in m using the defined engineering formula and the input values provided. Compression set depth is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Nip force per unit width = 100000
  • Logarithmic time factor = 2.8
  • Effective dwell time = 0.008
  • Blanket effective modulus = 1600000
  • Blanket compression set coefficient = 2.4E-12
  • Compression set power-law exponent = 0.85
  • Blanket viscoelastic relaxation time constant = 0.045

Expected Result:

  • Compression set depth = 1.927E-6

Engineering Interpretation:

Under the given input conditions, the calculated result is: Compression set depth = 1.927E-6 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

compression set depth = blanket compression set coefficient * pow(nip force per unit width / blanket effective modulus, compression set power-law exponent) * logarithmic time factor * (1 - exp(-effective dwell time / blanket viscoelastic relaxation time constant))
