Abstract

Laboratory and field experiments in wood engineering often rely on different types of devices to measure strain. Each type has certain limitations and characteristics that generally dictate its applicability to wood. Some of the issues related to using traditional strain measurement devices on wood and wood-based materials are discussed in this paper.
