Bonded Point-Supports: Understanding Today – Optimizing for the Future

Abstract

Experiments using material specimen of the Silicone adhesive on the one hand and several point support designs on the other hand provide valuable know-how for favourable layout from engineering point of view. The comparison of uni-axial material tests based on dog-bone specimens, of H-type specimens of ETAG 002 type and of circular and rectangular point supports show different working principles of the adhesive material. Test results on planar point supports and comparison with other point support designs show similarities in terms of applicable limit stresses. For advanced point support designs, these similarities might be affected by the support geometry leading to local stress peaks.
