Theoretical responses of different rheological models to a sinusoidal compression in a transient state

The sinusoidal compression imposed by the new device set up by SALE (INRA, Theix, France) is not an harmonic test. Therefore, a theoretical study of the deformation has been undertaken. The use of Carson-Laplace trans forms allows one to establish the response of a Burgers model with the Hencky strain specific of the test. Simulations of simple rheological behaviour (elastic, viscous, vicoelastic) are presented as reference for future analysis of more complex behaviours of foodstuffs.
