Calculation examples
Circular cylindrical shell with constant wall thickness, non-displaceable on both sides, axially displaceable rim
According to the specifications, the selection must first be made in the selection menu. By selecting the graphic in the selection menu, various examples are displayed.
In this calculation example, "circular cylinder shell with constant wall thickness" and "top RB2 - bottom RB2" are selected. Clicking "Next" takes you to the input/output mask for the calculation can make the necessary further entries.
1. The known input data are entered in any order into the corresponding fields of the input mask. Possible calculation steps are executed immediately.
2. Display of the input mask with input values and calculated values
3. Often, several paths lead to the goal.
4. For example, you can enter the wall thickness and the wall thickness undercut to have the program determine the effective wall thickness. However, if the wall thickness undercut is zero or the value of the minimum wall thickness of the apparatus is explicitly available to you, you can also enter the effective wall thickness directly and leave the Wall thickness and Wall thickness undercut fields blank.
5. In the lower part of the mask you will find calculation results displayed!
Calculation of buckling safety according to DIN 18800 part 4 for the cylindrical part (position 1) of a tank.

The calculation is performed automatically as soon as the input values allow a calculation. Input values are entered in black and calculated values in blue / bold.
In the example, the inner and outer diameters of the cylinder were calculated from the input values radius and effective wall thickness.
