The paper discusses some of computational problems which can arise during non-linear computational investigation of numerical models of concrete with use of a smeared crack models. Despite the long–term researches in this area (good overviews are available in (Baˇant and Planas, 1998) and in (Jir´ sek and Baˇant, z a z 2002)) there are still some areas which can make this type of modelling uneasy. The discussed constitutive model is based on smeared cracks and it uses equivalent constitutive one–dimensional material laws. Such models can be found both in ˇ professional (Voˇechovsk´ and Cervenka, 2002) and academic ﬁnite element codes. r y
