*PERFORMS LS-DYNA MATERIAL REMOVE STRAIN RATES*
===============================================

Removes strain-rate dependency from LS-DYNA material definitions by processing the keyword file and stripping rate-dependent curve/table references. Use this worker to collapse rate-dependent MAT cards to a single quasi-static curve before calibration or simplified simulations.

When to use

Tagged: ``curve``, ``keyword``, ``lsdyna``, ``mat_24``, ``material``, ``rate_dependency``, ``strain_rate``, ``table``.
