COMPUTE FLEXURAL MODULUS¶
Computes the flexural (bending) modulus of a specimen from a three-point bend test using the standard formula E = P·L³ / (4·b·d³·y). Use this worker when deriving stiffness from coupon-level flexural test data.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Load Value | loadvalue | scalar | 1 | ✓ | Applied maximum load P at mid-span (force units, e.g. N or lbf); default 1 — must be replaced with the measured peak load from the test. |
| Specimen Length Span | specimenlengthspan | float | 1 | ✓ | Support span length L between the two outer supports (length units, e.g. mm or in); default 1 — set to the actual gauge span used in the bend fixture. |
| Specimen Width | specimenwidth | float | 1 | ✓ | Cross-sectional width b of the specimen (length units, e.g. mm or in); default 1 — set to the measured coupon width. |
| Specimen Thickness | specimenthickness | float | 1 | ✓ | Cross-sectional thickness d of the specimen (length units, e.g. mm or in); default 1 — set to the measured coupon thickness; enters the formula cubed so accuracy is critical. |
| Deflection | deflection | float | 1 | ✓ | Mid-span deflection y corresponding to the applied load P (length units, e.g. mm or in); default 1 — set to the deflection value measured at the load point. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| math_flexural_modulus_output_1 | math_flexural_modulus_output_1 | scalar | Computed flexural modulus E = P·L³ / (4·b·d³·y) returned as a scalar in the same consistent force/length² units derived from the inputs (e.g. MPa if inputs are N and mm). |
