Plate characteristics, cyclic four-point bending span widths, cyclic fatigue initial maximum load levels, and step increments
| Plate type | Annealed? | Plate length/thickness/hole spacing (mm) | Span L o (mm) | Span L i (mm) | Start F max (N)/% of M y | Load step increment (N) |
|---|---|---|---|---|---|---|
| BFS Reconstruction | Y | 110/3.1/16 | 80 | 32 | 300/240 | 12.5 |
| MPS Straight | N | 106.5/2.5/16 | 80 | 32 | 200/160 | 12.5 |
| MPS Flex | Y | 82.5/2.5/12 | 60 | 24 | 153/90 | 17 |
L o outer span width, L i inner span width for four-point bending test fixture, M y bending moment at yield point (0.2 % offset method)
