摘要: The paper reviews transient moisture effects in various materials with emphasis on their viscoelastic properties and durability. first part of the review is dedicated to phenomenological aspects such as whole wood, plywood, particleboard, fibreboard, paper, natural synthetic fibres composite materials. Creep, creep recovery, dynamic response failure influenced by conditions are discussed relation system, extent rate change, loading modes, temperature levels, specimen sizes, type solvent preventive measures. second devoted discussion mechanistic models. Explanations phenomenon from a molecular standpoint assessed, compared depth so that one can gain deeper insight into part. main mechanisms include: (i) hydrogen bonding, (ii) slip planes (iii) crystallite slippage rotation.
