Incremental Formulation for Coupled Viscoelasticity and Hydrolock Effect in Softwood

Comparative investigation on viscoelastic and mechanosorptive creep behavior of two tropical hardwoods and one temperate softwood

“…Viscoelastic behaviour can be demonstrated by creep tests in a constant climatic environment (Navi and Heger 2005). When the effects of climatic variations under constant mechanical load are added to viscoelastic behaviour, wood exhibits another more complex behaviour called mechanosorption (Navi et al 2002;Nguyen et al 2016). An early work on mechanosorptive behaviour was carried out by Armstrong and Kingston (1960); they observed that the deflection of a wooden specimen was influenced by variations in relative humidity.…”
