*MATERIAL SPECIMEN GENERATOR — FSIP SHEAR COUPON*
=================================================

Generates an LS-DYNA 4ENF (4-point End-Notched Flexure) Mode II fracture coupon for adhesive Mode II calibration. The two material parameters SHRMAX and GCSHR are exposed as inputs so calibration sweeps can vary them without re-shipping the keyword deck. The rest of the deck is fixed.

When to use
-----------

Classification: **data**.

Tagged: ``adhesive``, ``calibration``, ``fracture``, ``keyword``, ``ls-dyna``, ``mat_169``, ``mat_arup_adhesive``, ``mode_ii``.
