Spotweld Data Components
Spotweld Data Components
For spotwelds the following data components are available.
| Component | THF (d3thdt) | XTF (xtfile) | LSDA (binout) | ASCII | |
| AX | Axial force | yes | yes | ||
| SH | Shear force | yes | yes | ||
| LE | Length | yes | yes | ||
| FT | Failure Time | yes | yes | ||
| FA | Failure | yes | yes | ||
| MM | Moment Magnitude | yes | yes | ||
| TO | Torsion | yes | yes | ||
| The following additional data components are also available for Solid Spotwelds and Spotweld Assemblies if the DCFAIL file is written. | |||||
| FF | DC Failure Function | yes | yes | ||
| NF | Normal Failure Term | yes | yes | ||
| SF | Shear Failure Term | yes | yes | ||
| BF | Bending Failure Term | yes | yes | ||
| AR | Spotweld Area | yes | yes | ||
The DCFAIL file contains additional data for spotweld solids and clusters models using the _DAIMLERCHRYSLER version of *MAT_SPOTWELD (this version of the material does not support beam elements).The file contains additional failure data showing how close to failure the spotweld is in tension, shear, bending and torsion, in addition it contains another copy the normal spotweld forces written to the SWFORC file.
The new data components appear under the SOLID and ASSEMBLY sub types within the SPOTWELD menu. If the SWFORC file is also present then the normal forces and read from the SWFORC file, if the SWFORC file doesn't exist but the DCFAIL file does then the data components (Normal, shear forces etc) that are mirrored in the DCFAIL file are read from there instead.
As the DCFAIL file only contains the ID's and not the types or each connection then it is not possible to tell from the DCFAIL file alone which items are solids and which ones are spotweld clusters. If the SWFORC file is present then T/HIS used the information in this file to match up the ID's and work out the type of each item in the DCFAIL file. If the SWFORC file isn't present then it attempts to use the data in the ZTF file to work out the types.
