ABSTRACT: This paper presents a rheological study of agricultural product and its viscoelastic behaviour, by EF through the objective numerical simulation tool based on parameters derived from experimental tests, mainly Young's
modulus, Poisson's ratio and thermal conductivity, to study the behaviour of raw potato (variety: spunta), to
perform creep and conformance at constant load and each numerical model. The times imposed in the model
and the strains recorded make it possible to determine the characteristic elastic part, the first and the second
part of the creep curve and the determination of the quantitative parameters (dynamic viscosity ƞ1, ƞ2, E1, E2)
of this biological material. These results which will be drawn present references to limit the maximum loads for
the resistance of the potato against damage, and to increase the yield of the fresh product in the transports,
storage and harvest also on the effect of temperature on the behaviour of potatoes under the conditions
encountered in its estimated cycles.
