Microscopic observation of tensile testing on leather fibre bundles

摘要

The simultaneous acquisition of data on tensile force and extension values, as well as sequences of microscopic images, enables the process of fibre extension and rupture to be optically traced and documented. This information reveals the way that the fibres crack. For example, it can show if either a cracking or a twisting of the sub-units occurs during the breaking process. Such information can be subsequently used to gain insight into ways to possibly improve behaviour, and within material modelling.
