The Comparative Analysis of Experimental and Numerical Results of Initial Phase of Plastic Deformation in Shields with Openings under Tension

Abstract:

The paper attempts to clarify the differences between theoretical and experimental values of elastic bearing capacity for shields with openings under tension. The discrepancies occur between the experimental and the FEM calculations results which were realized by team of Institute of Applied Mechanics of Cracow University of Technology.For the purpose of comparative analysis one performed FEM calculations of the 15CrMo steel shield of geometry which was the geometry of shields being the subject of the experiments. The material model assumed in the FEM calculations was the elastic-plastic steel with the small linear reinforcement. In the calculations it was failed to obtain analogous plastic deformation schemes as in the experiments. There was obtained a similarity between the plastic zones shape and dimensions obtained from FEM calculations and for plastic zones shape and dimensions from experiments for loadings which exceed the experimental elastic bearing capacity for about 20%.
