Nonlinear Creep Behavior of Spruce Wood at the Temperature of 180C
Introduction Mechanical properties of wood (biomaterial polymer), are affected by time of loading. Rheoiogical properties are defined as a change of stiffness or strength due to elapsed time or moisture content change under loading. Several approaches have been used to describe creep behavior in wood. Haque et al. showed that Kelvin model and Burgers model fitted the wood theology data satisfactorily. There are numerous studies dealing with temperature conditions up to 130℃ 2, 3, 1. The objective of this study was to check level of linear creep behavior and confirm applicability of a phenomenological approach based on spring-dashpot element models.
