CURVE GET CYCLIC DATA¶
Extracts cyclic (loading/unloading) segment data from a curve, splitting it into individual cycles or returning all cycles at once. Use this worker to isolate specific loading, unloading, or combined loading-unloading portions of a cyclic test curve for downstream analysis.
When to use¶
Classification: process.
Tagged: curve_transform, cycle_extraction, cyclic, fatigue, hysteresis, loading, unloading.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve In | curve_in | vector | — | Input curve (x/y vector) representing the cyclic signal to be decomposed; typically a force-displacement or stress-strain time history from a cyclic test. | |
| Scale X | scale_x | scalar | 1 | Multiplicative scale factor applied to the x-axis before cycle extraction (dimensionless); defaults to 1 (no scaling). | |
| Scale Y | scale_y | scalar | 1 | Multiplicative scale factor applied to the y-axis before cycle extraction (dimensionless); defaults to 1 (no scaling). | |
| Skip Negative | ignore_negative_x | scalar | yes | Whether to skip data points with negative x-values after scaling before computing cycle statistics; set to ‘yes’ (default) to ignore negative x, or ‘no’ to include all points. | |
| CN-WBAC | cyclenumber | scalar | -1 | Index of the specific cycle to extract (1-based integer); use -1 (default) to return data for all detected cycles. | |
| Type Of Data To Extract | type_of_data_to_extract | scalar | loading_unloading | Portion of each cycle to return: ‘loading_unloading’ (default, full cycle), ‘loading’ (ascending branch only), or ‘unloading’ (descending branch only). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_get_cyclic_data_output_1 | curve_get_cyclic_data_output_1 | vector | Extracted cyclic curve segment(s) as a vector, containing only the requested loading/unloading branches for the selected cycle(s). |
