Comparison of numerical simulation and experiment in case of bending test of composite rectangular tubes

Popis výsledku v původním jazyce

The design of a composite footbridge using a finite element method (FEM) model is the aim of the research project TA02010501. A box beam concept is used in the footbridge design. To validate the FEM model, bending tests of composite rectangular tubes were done. The aim of this work was to compare the failure of the tubes in case of the FEM model and the experiment and to determine a safety coefficient for the load capacity evaluation of the footbridge. Two types of samples were tested. Sample A consisted of two outer chopped strand mat (CSM) layers and two inner unidirectional (UD) layers. Sample B consisted of six biaxial non-crimp fabric (NCF) layers. Performed tests were numerically simulated using the Abaqus 6.12 finite element system. The maximumstress theory was used to determine failure. Analyses with and without large deformation assumption were compared. The type of the deformation assumption did not significantly influence results of the model of the sample B. However, signi
