1. Reference problem

1.1. Geometry

• \(L=200\mathit{mm}\)

• \(h=300\mathit{mm}\)

• \(a=10\mathit{mm}\)

Coordinates	\(X\)	\(Y\)
A	\(10.\)	\(0.\)
B	\(100.\)	\(0.\)
C	\(100.\)	\(150.\)
D	\(0.\)	\(150.\)
E	\(0.\)	\(10.\)
F	\(10.\mathrm{cos}(\frac{\mathrm{\pi }}{4})\)	\(10.\mathrm{cos}(\frac{\mathrm{\pi }}{4})\)

1.2. Material properties

The material is isotropic elastic whose properties are:

• Young’s module \(E=3\times {10}^{4}\mathit{MPa}\)

• Poisson’s ratio \(\mathrm{\nu }\text{}=0.25\)

1.3. Boundary conditions and loads

Imposed displacement:

• AB side: \(\mathit{DY}=0.\)

• Side OF: \(\mathit{DX}=0.\)

Pressure imposed on the CD side: \(p=2.5N/{\mathit{mm}}^{2}\)

1.4. Initial conditions

None
