Problem of stress concentration and deformation in the use of multilayer GFRP (Glass Fibre Reinforced Polymer) in bearing structures

The paper analyses a problem concerning concentrated stress in the use of multilayer GFRP carriers. Due to concentration of stress excessive deformation and local collapse occurs much sooner than the material stress peak is achieved. The paper shows the testing of the material samples and the carriers with two different spans. Also the linear and nonlinear numerical analysis was conducted. In the end the comparison of the results and a proposal for the design calculation is shown. Also the material improvement on the critical concentration places is proposed.
