Besides, some studies presented the impact of crack closure to crack growth in different temperatures, they only used the experimental method to research the crack closure property for limited metal material. Current research lacks a suitable analytical or numerical model to present the relation between crack closures and crack growth. Current research applied energy method such as Griffith Criterion to investigate the crack propagation, however, most of the literature not consider the thermal load's impact on the criterion when the loads were coupled. It means the Griffith Criterion and stress intensity factor should be temperature sensitive and time dependent under dynamic loads. Therefore, it is critical to develop or modify the Griffith Criterion to adapt the thermo-mechanical condition. On the other hand, Paris’ Law or its modifications are applied to predict the crack growth rate widely as a classical experimental model in much research. However, the study lacks a suitable analytical model to build the relation between crack growth rate and thermo-mechanical loads with the consideration of energy change due to thermal loads. Most of the research focused on the composite materials considered the delamination failure which is different from conventional materials. Moreover, very less research is available considering the impact of thermo-mechanical loads to this failure. Also, apart from composites, more and more polymer materials are applied in manufacturing with the development of FDM. After analyzing the relevant research most of these efforts consider the impact of mechanical loads on fatigue. However, less work considers the involvement of the thermal fatigue and fracture of polymeric materials. Therefore, still a comprehensive research is required to analyze the fatigue crack propagation of ABS structure under thermo mechanical loads. Arabi, H. and Sadeghi, B.M.
