After the deformation the stress decreases as a function

Reference no: EM13546862

A visco-elastic system is subjected to an instantaneous deformation of 100 %. The stress, necessary for this deformation, is 2 MPa. After the deformation the stress decreases as a function of time as displayed in the table below.
