*OFFSET BASE CURVE TO STRAIN RATES*
===================================

Offsets a quasi-static base curve along the stress/force axis to align it with a set of reference strain-rate curves. Use this worker when you need to synthesize a strain-rate-scaled version of a base material curve by anchoring it to existing rate-dependent reference curves.

When to use

Classification: **process**.

     - 
     - The base quasi-static stress–strain (or force–displacement) curve to be offset; supplied as a single XY vector. Leave unconnected only if the offset operation is not required.
   * - Ref Curves
     - ref_curves
     - vector
     - —
     - 
     - Collection of reference strain-rate curves (XY vectors) used as the target anchors for the offset calculation; each curve should represent a distinct strain rate of the same material.
