Szukana fraza: [Abstract = "A series of experiments \(tensile, compression and bending tests\) were carried out to identify its mechanical parameters. To determine the heterogeneity of analysed foam a Digital Image Correlation \(DIC\) technique, named Aramis, is applied in the paper. The results obtained from FE analyses are compared with the experimental results on full\-size plates carried out by the author and proper conclusions are drawn."]
