Stress distribution in sandwich beams under tension

摘要

This paper investigates the distribution of load in the skins of sandwich beams subjected to in-plane tension, via the action of shear lag. The investigation also includes the effect of the tapered reinforcement at the ends of the sandwich beams. A literature survey shows that a well-known shear lag theory is available which can be used to analyze special cases of beams without end reinforcement. A simple theory is proposed in this contribution to study the significance of the end reinforcement on the load distribution in sandwich beams Details of an experiment procedure carried out and some experimental results obtained are also presented. These experimental results provide some validate indication of the proposed simple theory presented.
