Acquiring the mechanical behaviour of a helical fibered cardiac scaffold propels the fabrication of a scaffold exhibiting similar properties with the native cardiac tissue. Selecting fiber-based scaffolds will contribute to mimicking the complex function performed during the muscle's expansion and contraction. In our study, we exposed fabricated electrospun samples to repeated multistep tension by applying and removing deformation in order to mimic the mechanical behaviour of helical fibered cardiac scaffolds. Since the fiber-based specimens exhibit viscoelastic behaviour, the transient responses to constant deformation caused stress relaxation and stress recovery. Nevertheless, stress softening and repeated buckling phenomena, which are viscoelastic characteristics, had an unexpected impact on the samples' behaviour, leading to inconsistent material characterization. Eliminating techniques are also explored to ensure representative results about the fabricated scaffolds' behaviour.
