CONVERT STRESS-TENSOR TO TIAXIALITY USING VON-MISES STRESS AND HYDROSTATIC PRESSURE¶
Converts a set of stress-tensor component curves (σ_x, σ_y, σ_z, τ_xy, τ_yz, τ_zx) into a derived scalar quantity using von Mises stress and hydrostatic pressure. Supports three output modes: triaxiality (η = p / σ_vm), hydrostatic pressure, or von Mises stress. Use this worker to prepare stress-state indicators needed for material failure and GISSMO calibration workflows.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve 1 | stresscomponents | vector | — | Time-history curves of the six independent stress-tensor components in order σ_x, σ_y, σ_z, τ_xy, τ_yz, τ_zx (vector/curve format); multiple element or integration-point curves may be supplied simultaneously. | |
| Return Type | return_type | list | triax | Selects the scalar quantity to compute and return: ‘triax’ (triaxiality η = hydrostatic pressure / von Mises stress, default), ‘pressure’ (hydrostatic pressure p), or ‘von-mises’ (von Mises equivalent stress σ_vm). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_stress_to_triaxiality_output_1 | curves_stress_to_triaxiality_output_1 | vector | Output curve(s) containing the computed scalar quantity (triaxiality, hydrostatic pressure, or von Mises stress) as a function of time, one curve per input stress-tensor set. |
