Life Prediction of Adhesive Systems

Joint life can be predicted using finite element analysis (FEA), linear-elastic fracture mechanics, and materials fatigue and fracture data. Strain energy release rate (G) is derived as a function of crack length from the fracture analysis, usually from a finite element model. This together with adhesive fatigue data is used to predict crack growth and fatigue life for the range of loads of interest. The methodology is being developed so that it can be used as a tool for computer aided engineering (CAE).
