MATERIAL SPECIMEN GENERATOR FOR DART IMAPCT¶
Generates a ready-to-run LS-DYNA dart-impact specimen deck conforming to either ASTM D3763 or ISO 6603 standards. It meshes a circular plate specimen at the requested element size, embeds the user-supplied material card, and emits a complete keyword file for downstream solver submission.
When to use¶
Classification: data.
Tagged: astm_d3763, circular_plate, dart_impact, iso6603, keyword_deck, ls-dyna, mat_elastic, mesh_size.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Specimen Mesh Size | mesh_size | scalar | 2 | Target element edge length for the specimen mesh in millimetres (default 2 mm); smaller values increase mesh density and solver runtime. | |
| Material Data | material_data | text | *MAT_ELASTIC 1,7.89e-9,210 | Raw LS-DYNA material keyword block (e.g. *MAT_ELASTIC with density, Young’s modulus) pasted as plain text; defaults to a generic steel elastic card if left unchanged. | |
| Additional Keywords | additionalkeywords | text | — | Any supplementary LS-DYNA keywords (contacts, boundary conditions, output controls, etc.) to be appended verbatim to the generated deck; leave blank if no extras are needed. | |
| Standard Type | standard | scalar | astm_3763 | Test standard that governs specimen geometry and loading conditions; choose ‘astm’ for ASTM D3763 or ‘iso6603’ for ISO 6603-2 (default: astm_d3763). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dart_model | dart_model | textarea | Complete LS-DYNA keyword deck (plain text) for the dart-impact specimen, including mesh, material, boundary conditions, and any appended keywords, ready for solver submission. |
