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.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Element Formulation | elform | scalar | 1 | Solid element formulation for the primary adherend section (*SECTION_SOLID secid=1). Exposed as IELFORM in *PARAMETER (referenced as &ELFORM). Default 1. | |
| Duration | duration | scalar | 100.0 | Total simulation / load ramp duration. Exposed as RETERM in *PARAMETER (referenced as &ETERM in *CONTROL_TERMINATION and the load curve end time). | |
| Load Magnitude | load_magnitude | scalar | 5.0 | Final ordinate of the prescribed-motion load curve (applied displacement). Exposed as RLMAG in *PARAMETER (referenced as &LMAG). | |
| Force Multiplier | force_multiplier | scalar | -1.0 | Scale factor on the prescribed-motion load (sign sets direction). Exposed as RFMULT in *PARAMETER (referenced as &FMULT). Default -1.0. | |
| Material Data (Full *MAT Card Override) | material_data | textarea | — | Full *MAT card to inject. When empty, a neutral non-proprietary placeholder MAT_ARUP_ADHESIVE card is emitted (no calibrated values) — supply the real material card here at runtime. | |
| Additional Keywords | additional_keywords | textarea | — | Optional free-text LS-DYNA keywords appended after the deck and before *END. | |
| Title | title | scalar | Sample FSIP Shear Coupon | Text that appears in the *TITLE block at the top of the generated keyword deck. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| material_specimen_generator_fsip_output_1 | material_specimen_generator_fsip_output_1 | text | Generated LS-DYNA keyword text for a 4ENF Mode II fracture coupon with the supplied shear-strength + Mode II fracture-energy parameters baked into the *PARAMETER block. |
