DESCRIPTION:Adhesive bonding is a widely used joining technique across var
 ious industries and is particularly common in composite structures within 
 the construction sector\, especially for the repair and strengthening of e
 xisting infrastructure. Extensive research has been conducted to understan
 d the behaviour of fibre-reinforced polymer (FRP) to concrete and FRP to s
 teel bonded joints\, leading to well-established design methodologies for 
 such interfaces in civil engineering applications.\n\nPrevious studies hav
 e shown that bonded interfaces are subjected to complex stress states\, an
 d numerous theoretical models—with varying levels of simplification—ha
 ve been developed to predict interfacial stresses. These models\, along wi
 th numerical approaches\, have been used to estimate key parameters govern
 ing the performance and failure of bonded joints\, including debonding mod
 es.\n\nWhile there is broad consensus on several aspects such as bond stre
 ngth\, effective bond length\, and bond–slip relationships\, discrepanci
 es remain regarding interfacial stress distributions\, behaviour under cyc
 lic loading\, and response under elevated temperatures. Moreover\, ongoing
  debate surrounds the suitability of homogenization approaches\, such as t
 raction–separation laws\, in accurately capturing the behaviour of bonde
 d interfaces.\n\nIn this talk\, I will provide a critical review of existi
 ng research on FRP-to-concrete and FRP-to-steel bonded joints. The discuss
 ion will cover their behaviour under quasi-static monotonic loading\, cycl
 ic loading\, and combined mechanical–thermal loading. Interfacial stress
  models and the appropriate use of homogenization techniques in modelling 
 bonded interfaces will also be critically examined.
