The values printed in the materials properties summary appear to be incorrect

We are often asked why the values shown on the summary page of the characteristics of the materials are incorrect.

On the same page, there is a note that clearly indicates the fact that the characteristics reported for the calculation may vary based on the type, conditions and other factors and to therefore refer to the calculation of the single component for the allowable value used in that calculation.

The discrepancy is due to the fact that the summarized values ​​concern only the material, taken outside the context of application. The same material, if used to calculate different components, can have different allowables.

In the summary, the general rules for calculating the allowables are applied.

When calculating the individual components, the specific rules for the type of component are applied (for example, in EN 13445 flanges define a different method of calculating the allowable under certain circumstances).

You must always check the calculation report of a component to verify the values ​​used in the calculation of that component.
