“…The basic material properties, namely the modulus of elasticity and the Poisson's ratio, for the non-linear elastic components of the model are given in Table 1 . Since the stiffness varies with age [ [39] , [40] , [41] ], the corresponding Young's moduli were considered as a function of age [ 42 ]. The densities were estimated to 1.0 ⋅ 10 3 kg/m 3 in broad accordance with corresponding parameters in other studies [ [43] , [44] , [45] , [46] , [47] ].…”
