Abstract

The characterisation of Brazilian P. edulis bamboo is presented as an example of the adoption of ISO 22157 test methods. Using digital imaging correlation (DIC), the behaviour of the bamboo material subject to mechanical tests, their interaction with boundary conditions, and the progression of damage during testing is illustrated. The DIC helped to identify and quantify specimen behaviour, particularly in the presence of a node. Nodes are shown to have a significant local effect on behaviour which can be mostly disregarded in compression and shear but are a weak link in tension. This behaviour is described as an artefact of the morphology of the bamboo fibres in the nodal regions. Specimen damage development was also described by DIC and the adoption of the limit of proportionality (LOP) as a measure of useful material capacity proposed. Additional recommendations related to the adoption of ISO 22157 are presented. (C) 2019 Elsevier Ltd. All rights reserved. (AU)
