MATERIAL SPECIMEN GENERATOR FOR PLATE JOINING SHEAR¶
Generates an LS-DYNA keyword deck for a plate-joining shear specimen used in weld/adhesive/clinch material characterization. Given joint geometry, sheet-metal thicknesses, material ID, and solver controls, it authors a ready-to-run input file that loads the joining region in pure shear. Use this worker when you need a parameterized shear coupon for calibrating joining-material failure models.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Joining Width | joining_thickness | scalar | 5 | Thickness of the joining element (e.g. adhesive layer, weld bead) in the through-stack direction, in mm; default 5 mm. | |
| Joining With | joining_width | scalar | 5 | In-plane width of the joining region (perpendicular to the shear loading direction), in mm; default 5 mm. | |
| SMT1 | sheetmetalthickness1 | scalar | 2 | Thickness of the first sheet-metal plate that forms one side of the joint, in mm; default 2 mm. | |
| SMT2 | sheetmetalthickness2 | scalar | 2 | Thickness of the second sheet-metal plate that forms the opposite side of the joint, in mm; default 2 mm. | |
| Joining Material ID | joining_material_i_d | scalar | 1 | LS-DYNA material ID assigned to the joining region (e.g. cohesive or solid element material card); default 1. | |
| Max Displacement | max_displacement | scalar | 20 | Maximum prescribed shear displacement applied to the specimen boundary in mm; controls the loading amplitude; default 20 mm. | |
| Termination Time | termination_time | scalar | 100 | LS-DYNA simulation end time in consistent time units (ms or s depending on model units); default 100. | |
| Time-history Interval | time-historyoutput_interval | scalar | 0.1 | Output interval for time-history (binout/d3thdt) data in the same time units as termination time; default 0.1 — decrease for finer force–displacement resolution. | |
| Binary Output Interval | binary-output_interval | scalar | 1 | ||
