Learning outcomes :
To understand the phenomena of paper and cardboard deformation induced by variations in environmental conditions and anisotropic (elastic) mechanical behaviour laws of paper or cardboard
To understand the influence of paper manufacturing conditions on the mechanical and hygroexpansive properties of paper
To understand the main phenomena of hygroexpansion, creep and buckling of paper or cardboard
To present the main methods, and measure deformations and stresses in materials
To list and state the laws of behaviour of materials
To present the complex (hygro-)mechanical behaviour of papers, the influence of drying, the hygroexpansion of papers, the creep of papers, the phenomenon of accelerated creep

The objectives are:
an improved knowledge of the deformation phenomena of paper and boards that are related to modifications of the environmental conditions,
a better understanding of the mechanical (elastic) anisotropic constitutive laws for papers and boards
a better understanding of the effects of manufacturing conditions on the hygroexpansive and mechanical behaviours of paper
a first introduction to creep phenomena.
Introduction to hygroexpansion, creep and buckling phenomena of papers and boars. Definition of strain and stress measurements. Constitutive laws of materials. Hygro-mechanical behaviour of paper. Influence of drying. Hygroexpansion of paper. Creep and accelerated creep.
Physics of paper (1st year). Strength of materials.
