Figure 1.1-a : geometry of the cracked plate

All dimensions are in millimeters.

1.2. Material properties#

Young’s module \(E\mathrm{=}200000\mathit{MPa}\)

Poisson’s Ratio \(\nu \mathrm{=}0.3\)

1.3. Boundary conditions and loads#

Boundary conditions:

Point \({P}_{1}\): \(\Delta X\mathrm{=}\Delta Y\mathrm{=}0\)

Point \({P}_{2}\): \(\Delta Y=0\)

Charging:

Strength: \(P\mathrm{=}1000N\)

The load ratio is set to zero. The force value \(P\) given above is therefore the maximum value of the fatigue cycle.
