Cylindrical specimens of Agar gel (5%), apple flesh, and potato tissue were subjected to large uniaxial compressive deformation and then the stress was allowed to relax. The relaxed moduli as well as the relaxation curves shape characteristic constants were calculated and plotted vs the initial stress or the fixed strain. The latter relationships revealed that there are early quantitative indications of failure well before this is indicated in the force deformation relationship.
