Mechanical Properties. The load on the cladding depends the mechanical evolution of the fuel in the reactor since it governs the fuel- cladding mechanical interaction (FCMI), which becomes significant during permanent low power operation or in case of a power increase after a long low-power operation. The mechanical properties also come into play in gap closure, which has a supreme influence on the temperature of the fuel and the corrosion of the cladding, but whose mechanisms are largely unknown.
Mechanical Properties. Tensile strength of PVC plasticized by DINP is similar to that of PVC plasticized by DEHP, as reported in Figure 6 a), extracted from [1]. In this case, Placard, which lowers the strength by a higher amount (Figure 6 b)), is more efficient than DEHP and DINP (a plasticizer, softening the polymer, is expected to decrease the tensile strength). In Figure 6 a), the tensile strength of PVC plasticized by 70 phr of DEHP can be estimated to be, by the linear fitting, And the tensile strength of PVC plasticized by DINP: Therefore almost the same value of strength. Instead, by Figure 6 b) the tensile strength of PVC with Placard S29 is 20% lower than that of PVC plasticized with DEHP, and the tensile strength of soft PVC with placard S32 is 15% lower than that of soft PVC with DEHP. Addition of Placard involves a decrease of the strength by a factor of 20% (for S29) and 15% (for S32) compared to DEHP and DINP. a) b) (MPa) T S291 S32 DEHP Figure 6: Tensile strength comparison a) between DEHP and DINP plasticised PVC and b) between soft PVC samples with DEHP and Placard.

Mechanical Properties. The ligaments were modelled using non-linear spring elements with a damping coefficient of =900 Nm/s (Xx Xxxxx et al. [45], =300Nm/s, Dauvilliers et al. [69], =2000Nm/s). To define the behaviour laws of each ligament in both the lower and upper cervical spines, we referred to two complementary studies by Xxxxxx et al. [44] and Xxxxxxxxxx et al. [53, 54]. The Chazal et al. study [44] highlights the non-linear viscoelastic behaviour of ligaments whereas Xxxxxxxxxx et al. [53, 54] gives information on their failure properties. Concerning the intervertebral disks the hypothesis of a homogeneous linear elastic isotropic material was considered with a Young modulus of 100 MPa and a Poisson's ratio of 0.3. These values are situated between the extreme values related in the literature which represents a global behaviour of this structure (Kleinberger [61], Dauvilliers et al. [60]). The cervical vertebrae were declared as rigid bodies. The mechanical characteristics in terms of mass and inertias are taken from the work of Xxxx et al. [46]. Finally for the muscles a viscoelastic law has been implemented based on the Chawla et al. [43] study. Mechanical properties are listed in Table 9. Table 9.
