Abstract
Experimental soy flour extrudates, prepared under different processing conditions were tested in tension by an Instron Universal Testing Machine. All the extrudates exhibited a nonlinear stress‐strain relationship that is indicative of progressive development of structural failure. Complementary relaxation curves at three prefailure deformation levels were linearized and used for calculation of asymptotic relaxed moduli (also called equilibrium moduli). The relationship between the module and the strain or the initial stress indicated that both the break elongation and the ultimate strength could independently be estimated from the relaxation data. A mathematical and computer procedure for such predictions is described and its applicability demonstrated with experimental results.This publication has 10 references indexed in Scilit:
