1.2. Material properties#

  • Steel

  • \(E\mathrm{=}\mathrm{2x1011}\mathit{MPa}\)

  • \(\nu \mathrm{=}0.3\)

  • \(\rho \mathrm{=}7800\mathit{kg}\mathrm{/}{m}^{3}\)

1.3. Boundary conditions#

Calculating kinetic energy from speed \({E}_{c}\mathrm{=}\frac{1}{2}{V}^{T}MV\):

  • A uniform speed is imposed:

  • to \(t\mathrm{=}\mathrm{1s}\): next \(X\) of \(1.5m\mathrm{/}s\)

  • to \(t\mathrm{=}\mathrm{2s}\): following \(X\) of \(1.5m\mathrm{/}s\) and following \(Y\) of \(2.5m\mathrm{/}s\)

1.4. Initial conditions#

None.
