LINEAR ELASTICITY, THERMOELASTICITY AND VISCOELASTICITY

Une loi est un modèle qui nest plus (et pas encore!) contesté.

Hooke (1676), Young (1807), Cauchy (1822) and Timoshenko (1934) have said almost everything about the linear-elastic behaviour of materials. In this field, we will therefore limit ourselves to giving a summary in the form of formulae. However, we will deal with anisotropic elasticity, which is so important for composite materials, and the identification of the coefficients. The term elasticity is taken here to mean the reversible deformations mentioned in Chapter 3. Neither thermal dissipation (thermoelasticity) nor mechanical dissipation (viscoelasticity) is excluded.

Thermoelasticity introduces several additional coefficients ...
