Title: Non Linear Viscoelastic Behavior Of Spherical Fruits
Author: Linares A.W.
Dal Fabbro I.M.
Abstract: This work presents a study of contact stress phenomena in spherical fruits which generates non-linear relations for force and deformation. The material viscoelastic behavior is then associated with the non-linear relations due to the geometry of the body, generating a non linear viscoelastic problem. Such a non-linearity is called geometric non linearity. Elastic-Viscoelastic correspondence principle can not support the present case due the changes in boundary conditions. A technique was developed to measure the contact area and by means of the Hertz Contact Stress Theory, a function g (t) was defined, which is strongly influenced by force and deformation rates.
