Adhesives are widely used in optomechanical structures for bonding optical components to their mounts. The main
advantage of using adhesives is the excellent strength to weight ratio. Adhesive bonding is seen as a desirable joining
technique as it allows for greater flexibility in design. A disadvantage of adhesives however is the limited dimensional
stability and loadability. To design stable optical mounts, accurate prediction of stresses and deformation is therefore
needed.
Adhesives show strong temperature and loading history dependent behavior. Viscoelastic material models are needed for
accurate prediction of stresses and strains in bonded joints. However, representative material data for adhesives is
difficult to find.
In this research, an experimental framework is build up to determine relevant mechanical properties of adhesives for
improving stress and deformation prediction. This paper shows the results of the characterization experiments and
modeling techniques. Also the implementation of material models in finite element code is briefly discussed. The
obtained models are used in the mount design in the EUCLID and TROPOMI programs as described in “Ultra stable isostatic
bonded optical mount design for harsh environments, J.A.C.M Pijnenburg et al” (this conference).
