Description
Return blank-corrected cone penetration resistance.
Soil bench and profile terms depend on geometry, reference origins, heat-capacity bases and sign conventions. A pressure, stress or strain is a limited measured/model quantity rather than a complete soil-strength, heat-transport or field-state assessment. Reference lines and physical coefficients are supplied rather than inferred.
Return blank-corrected cone penetration resistance.
When to use this tool
Use Soil Penetration Cone Area Factor when checking the stated soil geometry, thermal, mechanical or measurement convention.
How to use the tool and how it works
- Enter force, coneDiameter, blankForce. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read resistance. Use the output convention below.
Return blank-corrected cone penetration resistance. Require coneDiameter > 0; resistance = 4*(force-blankForce)/(pi*diameter²).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| force | Force | Required. Finite number. |
| coneDiameter | Cone Diameter | Required. Finite number; strictly above 0. |
| blankForce | Blank Force | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| resistance | (force-blankForce)/(π*coneDiameter²/4); may be negative. | Required. Finite number. |

}Limitations and assumptions
- Negative resistance is retained; cone geometry, calibration, insertion rate and a valid soil-strength or machinery-safety interpretation are not verified.
- 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 calibrated measurements and an appropriate complete soil/engineering model for material properties, field behavior or safe practical loading.
