Pin-Contact Behaviour of Composite Sandwich Structures Under Compressive Bearing Load

  • Guido Di BellaEmail author
  • Luigi Calabrese


The aim this research is to investigate the pin-sandwich contact behaviour of some sandwich composites structures when submitted to compressive bearing loads. A preliminary set of flatwise and edgewise compressive tests and three point flexural tests were performed to get information on the mechanical behaviour of the sandwich structures under different load conditions. The influence of two different manufacturing procedures on the bearing strength is evidenced. The experiments show that the bearing loads increase with the pin diameter, while the bearing stress depends in a different way of the pin diameter for the two kind of procedures employed. In addition a simplified numerical model is proposed to evaluate the stress/strain distribution in the sandwich structure under compressive bearing load, by employing a commercial code. The comparison of numerical results with experiments shows the accuracy of the model.
