\subsection{Exercice 2}

|

\begin{align*}
|
||||
\left\{\begin{aligned}
|
||||
x_1 &\approx \phi^Tx_{1d}(t) \\
|
||||
x_2 &\approx \phi^Tx_{2d}(t)
|
||||
\end{aligned}\right. & &
|
||||
\left\{\begin{aligned}
|
||||
e_1 &\approx \phi^Te_{1d}(t) \\
|
||||
e_2 &\approx \phi^Te_{2d}(t)
|
||||
\end{aligned}\right.
|
||||
\end{align*}
|
||||
|
||||
En utilisant la première ligne de l'équation 1, on trouve :
|
||||
|
||||
\begin{equation*}
|
||||
\int\phi(\zeta)d\zeta\times\phi^T\dot{x_{1d}} = \int\phi(\zeta)d\zeta\times\frac{\partial^2}{\partial\zeta^2} = \ddot{\phi}(\zeta)^Te_{2*d}
|
||||
\end{equation*}
|
||||
|
||||
\begin{equation}
|
||||
\underbrace{\int_{0}^{L}\phi(\zeta)\phi(\zeta)^Td\zeta}_\text{E}\times\dot{x_{1d}} = \left(\int_{0}^{L}\phi(\zeta)\ddot{\phi}(\zeta)d\zeta\right)e_{2d}
|
||||
\end{equation}
|
||||
|
||||
Intégration par partie (IPP) :
|
||||
|
||||
\begin{equation*}
|
||||
\int_{0}^{L}u\cdot \dot{v} d\zeta = [u\cdot v]_{0}^{L} - \int_{0}^{L}\dot{u}\cdot v d\zeta
|
||||
\end{equation*}
|
||||
|
||||
Dans notre cas :
|
||||
|
||||
\begin{align*}
|
||||
\left\{\begin{aligned}
|
||||
u&=\phi(\zeta) \\
|
||||
\dot{v} &= \ddot{\phi}(\zeta)^T
|
||||
\end{aligned}\right. &
|
||||
\Rightarrow\left\{\begin{aligned}
|
||||
\dot{u} &= \dot{\phi}(\zeta) \\
|
||||
v &= \dot{\phi}(\zeta)^T
|
||||
\end{aligned}\right.
|
||||
\end{align*}
|
||||
|
||||
On applique plusieurs fois :
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
\int_{0}^{L}\phi(\zeta)\ddot{\phi}(\zeta)^T d\zeta &= [\phi(\zeta)\dot{\phi}(\zeta)^T]_{0}^{L} - \int_{0}^{L}\dot{\phi}(\zeta)\dot{\phi}(\zeta)^T d\zeta \\
|
||||
&= \phi(L)\dot{\phi}(L)^T - \underbrace{\phi(0)\dot{\phi}(0)^T }_\text{=0} - \int_{0}^{L}\dot{\phi}(\zeta)\dot{\phi}(\zeta)^T d\zeta \\
|
||||
&= \phi(L)\dot{\phi}(L)^T - \dot{\phi}(L)\phi(L)^T + \underbrace{\dot{\phi(0)}\phi(0)^T }_\text{=0} + \int_{0}^{L} \ddot{\phi}(\zeta)\phi(\zeta)^T d\zeta \\
|
||||
&= \phi(L)\dot{\phi}(L)^T - \dot{\phi}(L)\phi(L)^T + \int_{0}^{L} \ddot{\phi}(\zeta)\phi(\zeta)^T d\zeta = D
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
On continue avec ça en remplaçant dans l'équation 2 :
|
||||
|
||||
\begin{equation*}
|
||||
\Rightarrow \boxed{E\dot{x}_{1d} = De_{2d}}
|
||||
\end{equation*}
|
||||
|
||||
Puis on a dans la deuxième ligne de l'équation 1 :
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
\phi^T(\zeta)\dot{x}_{2d} &= - \frac{\partial^2}{\partial\zeta^2} (\phi(\zeta)^T e_{1d}) - q(\zeta, t) \\
|
||||
\int_{0}^{L} \phi^T(\zeta)d\zeta\times\dot{x}_{2d} &= -e_{1d}\int_{0}^{L}\phi(\zeta)\ddot{\phi}(\zeta)^T d\zeta - \underbrace{\int_{0}^{L}\phi(\zeta)q(\zeta,t)d\zeta}_{=F_{ext}}
|
||||
\end{aligned}
|
||||
\end{equation*}

||||
