Abstract: Two independent approaches to predict the restraint-induced macrocrack patterns in walls
have been recently proposed by the authors [1, 2]. The model of Knoppik-Wróbel and
Klemczak [1] is fully numerical whereas the approach of Schlicke and Tue [2] is a simplified
engineering model on the basis of analytical considerations. Both approaches are macroscopic
solutions aiming at a robust prediction of macrocrack patterns with respect to its main driving
forces. Both accept a certain level of simplification to ensure a broad applicability, however,
their reliability was verified by satisfying results of recalculations of practical observations, as
presented e.g. in [4, 6].This contribution presents both approaches and compares the results of
each for a given example. Besides computational aspects, mechanical background of the
restraint-induced cracking is outlined with special regard to relevant material properties,
geometry and restraint situations.
