Title: Use of master curves based on time-temperature superposition to predict creep failure of aluminium-glass adhesive joints
Issue Date: 2017
Abstract: Advancements in materials technology and the use of innovative designs have led to extensive application ofadhesive bonding techniques in the electric appliance industry. While the static strength of such joints issufficient for the intended applications, long term durability remains a major concern, mainly due to creepeffects. Conventional creep testing can be performed at the service temperature but it is a long test that can takedecades, although it can be accelerated using high temperatures. In this work, glass-aluminium joints werestudied under static and creep loads. Glass-aluminium specimens were subjected to creep testing at varioustemperatures. Using the time temperature superposition principle, the results of these individual creep testswere combined in a master curve that approximates the creep behaviour of the adhesive joint in a long timeperiod. These master curves were used to guarantee a minimum service life of the joint.
