Analytical verification example

Fig. A1-1The 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).
