To discuss the capability of the extended Schapery model to describe the strain recovery, it is necessary to predict the strain recovery after the ratcheting test, besides the creep and its recovery which has been discussed above and shown in Fig.
Most of rubber components endure cyclic loading during their service, and a nonzero mean stress during cyclic loading may cause an accumulation of strain, which is known as ratcheting phenomenon and ratcheting strain is the strain accumulation of material under unsymmetrical cyclic stress (1).
The ratcheting deformation (cyclic creep) accumulates from the very beginning of cyclic loading.
One such strain-controlled cyclic plastic excursion is generally termed as low cycle fatigue (LCF), while a stress-controlled asymmetric cyclic loading is termed as ratcheting. Ratcheting leads to permanent accumulation of plastic strain and consequence to early damage to the material.

Under the stress-controlled asymmetric cyclic loading, i.e., ratcheting, the inelastic deformation will progressively accumulate during the loading process.
