101 If test results do not agree with the analysis a change of few
material parameters in the analysis may create agreement between
test results and analysis. Such changes should be avoided and shall
be made with great caution.
Sec.10 E
102 Material parameters may be changed if the results can be confirmed
by independent tests on the material level.
Sec.10 E
103 If such tests cannot be made the analysis is closely linked
to the particular test geometry. Such an analysis shall not be used
for other geometry or loading conditions unless it can be shown
that the adjusted material parameters have a physical meaning.Guidance note:
Changes of material parameters due to damage, like matrix cracking,
as described in Section 4 can be made. These values are based on
independent material tests and are needed for a non-linear analysis.---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
