Techniques for post-fracture analysis

International audienceFracture observation is one of the key ways to understand the behavior of bonded assemblies. The plural science of bonded assemblies includes three main areas such as polymer sciences, physical chemistry of surfaces and interfaces, and mechanics. Solving the equation of adhesion needs intersection of all these aspects. Moreover, this multi-physics science is also a multi-scale one. Understanding surface fracture deals with all these aspects. This chapter presents three types of measurement systems: microscopy, compositional analysis/material identification, and mechanical observations. A table sums up an exhaustive list of the major observation devices and precise references of works that use these types of methods. Then, the main methods are detailed with macroscopic and mesoscopic observations, microscopic observation, physicochemical analysis, and mechanical observations
