The objective is to remodel experiments that have been conducted over the past
decades, while accounting for the temperature gradient and inclusions such as salt-
Experiments usually cover 3-point bending tests, 4-point bending tests and cantilever
beam tests. Each of these tests has particular features and effects on the developing
stresses which are to be analysed. Published studies claim that salt-brine voids and
the size to test specimens are the most influencing parameters.
The scope of this work is to verify or challenge the existing state of the art and to find
a possible explanation for some of the occurring scatter in tests.
