Abstract
Aspects of the mathematical modeling and computer prediction of deformation processes in polymeric parachute straps are examined. The computer methods developed on the basis of the mathematical model of viscoelasticity to predict relaxation and creep in the straps make it possible to calculate deformation and relaxation processes and the straps’ relaxational and deformational characteristics with a high degree of accuracy. Methods that were developed to divide total strain into its components also allow evaluation of the straps’ elastic and viscoelastic properties, which play an important role in choosing materials that have the requisite deformation properties.
