Determination of the material properties of an epoxy and MS-polymer for adhesive point-fixings

Adhesive point-fixings are being used more frequently because of their numerous advantages compared to traditional bolted connections, such as a better load introduction, the absence of drilling holes in the glass and increased thermal performances. For the analysis of such fixings the use of finite element analyses is necessary. The adhesive properties in these finite element analyses are presented on the basis of stress-strain curves. The determination of the stress-strain curves is done by experimental testing on bulk material of the adhesive. With these tests the displacement rate reliance can also be studied. In this contribution, the fabrication and testing of test samples is described for two selected adhesives. The experimental data show that the selected adhesives behave stiffer under tension as the displacement rate is decreased.
