AWG CI Test Case 3: Seat Belt Stretch Test Simulation
| Image: | |
| Animation: | Test Case 3 Animation |
| Description: | Force-deflection data from a seat belt tensile test was used to define *MAT_FABRIC input. This material input was then used in a model of the test to compare the analytical cross-section forces at the center of the seat belt using both quad and tria shell elements with the test force-deflection data. In the analysis, the top belt is meshed with tria shell elements and the three meshes below use quad shell elements. The tria and middle quad shell element meshes are stretched to the test deflection while the top and bottom shell element meshes are stretched to +30% and -30% of the test deflection, respectively. |
