1. Reference problem#

1.1. Geometry#

A bar of length \(L\mathrm{=}\mathrm{10m}\), along the \(X\) axis, modelled by 10 discrete elements with 2 knots.

1.2. Material properties#

Each discrete element has a stiffness: \(k\mathrm{=}1000N\mathrm{/}m\)

1.3. Boundary conditions and loads#

In \(x\mathrm{=}0\)

\(\mathit{dx}\mathrm{=}\mathit{dy}\mathrm{=}0\)

In \(x\mathrm{=}L\)

\(\mathit{Fx}\mathrm{=}\mathrm{10N}\)
