Description
  • The articleis primarily focused on negative efect of perfect numerical model symetry when it is for inverse identification of material model parameters for FRC. It is shown that if the model constructed in finite element (FEM) package is perfectly symmetric the identified material parameters may significantly differ from those obtained with nearly identical model wiith disturbed symmetry. By the identified parameters, we mean parameters leading to model response identical with experimentally obtained response. The presented numerical study is based on previous work by the autors and computational results are compared with experimental series on modulus of rupture test of FRC. In particular, we present comparisons of four point bending beams. In addition, the paper discusses the choise of an ideal shape of tensile softening for the used FRC material.
