Different models were simulated to assess the role of segmental parameters on active material calibration. The passive material properties were also calculated by the material calibration platform (Fig. 2). In scenario 6, the contraction in segments 3–6 was separately determined because the differences between the longitudinal and experimental strains were higher in segments 3–6.
