“…The use of backface strain measurements obtained during crack propagation and their exploitation have been previously detailed [27,33]. The method is based on measuring the (mainly negative) strain on the obverse surface(s) of the bent adherend(s), away from the adhesive layer, and analysing this by using expressions found from simple beam on elastic foundation models.…”

“…(7) and (8) are solved with k ¼ 0. For more details we refer the reader to [27]. Regarding the methodology used, the backface strain of the adherends, e s , as measured, can be related to the usual Timoshenko beam equation by: load-displacement curve in which it can be seen that, initially, load increases virtually linearly up to a peak value.…”

“…[5] Studies have been conducted that either evaluate the mechanical behaviour of the adhesive bonds that join aluminium with a composite [6][7][8] or provide an experimental procedure that measures the adhesive bond strength of a joint between a composite and steel. [9][10][11][12] Jumel et al [13] analysed the propagation of the crack and the process zone with end-notched flexure (ENF) specimens for adhesive bonding of aluminium/epoxy This test is presented for exploitation with a new experimental methodology using the backface strain monitoring technique. Stresses and strains in both adherents and the adhesive layer have been evaluated.…”

“…Jumel et al [68] analizaron la propagación de la grieta en probetas para ensayos por flexión con grieta en el extremo, End Notched Flexure (ENF), de uniones de aluminio con adhesivo epoxi. Se evaluaron tensiones tanto en adherentes como en la capa adhesiva.…”
