ALKOC LABS — SYNTHETIC EXAMPLE WORKFLOW

fatigue-load · v0.6.0

Inputs (with supplied units)
{
  "definition": "Maximum load + load ratio",
  "maximum": {
    "value": 20,
    "unit": "kN"
  },
  "ratio": 0.1,
  "signConvention": "Tension positive; compression negative",
  "dataOrigin": "Synthetic example"
}

Results
Maximum load: 20 kN
Minimum load: 2 kN
Mean load: 11 kN
Amplitude: 9 kN
Range: 18 kN
Load ratio R: 0.1

Method
Fmin = R × Fmax; Fmean = (Fmax + Fmin) / 2; Fa = (Fmax − Fmin) / 2; ΔF = Fmax − Fmin. R = Fmin / Fmax requires Fmax ≠ 0. Calculated by the Fatigue Workbench load-cycle core (tools.js computeLoads). Definitions: https://alkoclabs.com/resources#load-definitions

Limitations
• Synthetic inputs; not measured test data.
• Cycle descriptors only: no fatigue life, material strength, test-standard compliance or safety conclusion.
• No specimen area, material or crack geometry is inferred.
