1.1. Geometry

1.2. Material properties

The properties of the material constituting the plate are:

\(E\mathrm{=}2.{10}^{11}\mathit{Pa}\)	Young’s module
\(\nu \mathrm{=}0.3\)	Poisson’s ratio

1.3. Boundary conditions and loads

Boundary conditions: Embedded \(\mathit{AD}\) side

We are looking for the successive states of equilibrium under the load imposed on side \(\mathit{BC}\):

\(p(t)={p}_{\mathrm{cr}}t\)
with	\(t\)	pseudo_temps
	\({p}_{\mathrm{cr}}\)	Euler critical load

The load applied corresponds to the critical load of Euler \({p}_{\mathit{cr}}=\frac{{\mathrm{\pi }}^{2}EI}{4{L}^{2}}=\mathrm{1124,21}N\)
