An overview is given of the development of methods for the prediction of fatigue driven delamination growth over the past 40 years. Four categories of methods are identified: stress/strain-based models, fracture mechanics based models, cohesive-zone models, and models using the extended finite element method. It is highlighted that most models are phenomenological, based on the observed macro-scale behaviour of test specimens. It is suggested that a more physics based approach, focusing on elucidating the mechanisms involved, is needed to come to a full understanding of the problem of delamination growth.

“…Thus equation 1 is equivalent to using the stress intensity factor to correlate with delamination growth rate when m = 0.5n. Ratwani and Kan themselves state: "Assuming the delamination in the composite to behave like a crack, the power m in [equation 1] may be taken as 0.5n [17]".…”

“…Frequency effects were found to profoundly influence the fatigue behavior of cross-ply and angle ply laminates. Effect of biaxial loading (Ellyten and Martens 2001), twostage axial loading (Found and Quaresimin 2003), variable amplitude loading (Paepegem and Degrieck 2001), multi-stage loading (Clark et al 1999), compression-compression fatigue loading (Ratwani and Kan 1980, Soutis et al 1991, Choi et al 2002, and tension-compression fatigue loading (Rotem andNelson 1989, Gamstedt andSjogren 1999) have also been investigated for different types of composite materials. An excellent review of fatigue behavior under different loading conditions is compiled by Gamstedt and Anderson (2001) as well as Harris (2003).…”

“…Although tension-tension fatigue modeling received wide attention, compressioncompression stiffness driven fatigue model is found to be none which may be attributed to this rare type of loading. Analysis reported is mainly focused on fatigue life prediction (Ratwani andKan 1980, Dadkah et al 1995). Based on continuum damage mechanics (CDM) Xiong and Shenoi (2004) proposed a two stage damage theory on fatigue damage and life prediction of composites under compression-compression fatigue loading.…”

AHMAD, IFTEKHAR. Shear Response and Bending Fatigue Behavior of Concrete-Filled Fiber Reinforced Polymer Tubes. (Under the direction of Amir Mirmiran.) Recent field applications and research findings have demonstrated the effectiveness of concrete-filled fiber reinforced polymer (FRP) tubes (CFFT) as an efficient and promising hybrid system for designing main components such as pier columns, girders and piles for a bridge system. The vision was to provide a cost-competitive unified system composed of FRP/concrete hybrid members, which may act as a viable alternative to conventional reinforced and prestressed concrete structural systems. To achieve their broad-based implementation in civil infrastructure, understanding of their behavior and developing analytical tools under full spectrum of primary and secondary load demands are essential. Response characterizations under primary load demands namely, axial compression, flexural and axial-flexural, and seismic loadings have already been reported. However, investigations under primary shear and secondary fatigue load demands remain to be addressed. The present study consists of two phases. In the first phase, an experimental and analytical investigation was undertaken to characterize the behavior of a CFFT beam. Study on shear was primarily focused on the deep beam behavior. Comparisons of behavior of deep, short and slender beams were also highlighted. A strut-and-tie model approach, pertinent to analysis of deep reinforced and prestressed concrete members, was proposed to predict the shear strength of deep CFFT beams. Prediction showed good agreement with test results. It was concluded that shear failure mode is only critical for beams with shear span less than their depth.
