Abstract (EN):
Advancements in materials technology and the use of innovative designs have led to extensive application of
adhesive bonding techniques in the electric appliance industry. While the static strength of such joints is
sufficient for the intended applications, long term durability remains a major concern, mainly due to creep
effects. Conventional creep testing can be performed at the service temperature but it is a long test that can take
decades, although it can be accelerated using high temperatures. In this work, glass-aluminium joints were
studied under static and creep loads. Glass-aluminium specimens were subjected to creep testing at various
temperatures. Using the time temperature superposition principle, the results of these individual creep tests
were combined in a master curve that approximates the creep behaviour of the adhesive joint in a long time
period. These master curves were used to guarantee a minimum service life of the joint.
