| Abstract: | Evaluation of stress states for the experimental determination of the shear modulus of cellular materials The experimental determination of the shear modulus of materials proves to be problematic in practice. The different methods do not only preduce the desired pure shear stress state. In this paper, starting from several experimental implementations of the shear test, possible sources of errors in determination of the shear modulus are discussed. An estimation of the possible error is calculated by numerical simulations. Two examples from the field of cellular metals are given to illustrate the effect of just an approximate realization of the pure shear stress state. |
