A1Problem description
The simple plate system outlined above (edge lengths = 1 m, acute angle = 30 degrees) was investigated with a surface load in the z-direction of p = -0.7 \mathrm{kN/m^2} was investigated, taking into account an isotropic material (steel) with a modulus of elasticity of 210*10³ \mathrm{MN/m^2} and a Poisson’s ratio of 0.3. The thickness is 10 mm, and the plate is hinged at all four corners in the vertical direction.
The problem is to find the maximum principal stress on the underside of the plate at point m (the centre of the plate).
Es wurde das oben skizzierte einfache Plattensystem (Kantenlängen = 1 m, spitzer Winkel = 30 Grad) mit einer Flächenlast in z-Richtung von p = -0.7 \mathrm{kN/m^2} untersucht, wobei ein isotropes Material (Stahl) mit einem E-Modul von 210*103 \mathrm{MN/m^2} und einer Querdehnzahl von 0.3 berücksichtigt wurde. Die Dicke beträgt 10 mm, und die Platte ist rundherum in vertikaler Richtung gelenkig gelagert.
Gesucht ist die max. Hauptspannung an der Plattenunterseite im Punkt m (Plattenmitte).
