“…Furthermore, this suggests the importance of correctly defining the materials’ properties in certain product areas, such as stitched and perforated ones. In existing studies [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ], the properties are considered homogeneous over the entire surface of the footwear’s upper.…”

“…On the other hand, the available data for simulating a shoe’s upper assembly are limited due to the large variety of materials and manufacturing operations applied to these materials. The entire footwear product, including uppers, is rarely evaluated using finite element analysis because of the difficulty of experimental control [ 24 , 25 , 26 , 27 ]. Ruperez et al [ 28 ] described the mechanical behaviour of two types of calfskin for uppers by calculating Young’s modulus and Poisson’s ratio from the tensile test, intending to use these data to simulate the behaviour of the footwear.…”

“…The regular samples were cut in parallel and perpendicular to the backbone from the shoulder, butt and belly areas. In other studies, the properties of upper assembly are considered homogeneous over the entire surface of the footwear’s upper [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. However, footwear is a structural complex multilayer product, where its parts/components are organised into groups and subgroups.…”

This paper aimed to define two critical mechanical properties of leather—Young’s modulus and Poisson ratio—essential to the virtual simulation of the behaviour of the footwear uppers against the manufacturing operations of stitching and perforating. The following technological aspects were considered to analyse the materials from manufacturing conditions point of view: the number of layers (one layer and two layers), the nature of the materials used for uppers subgroups (calfskin-outer upper, sheep leather-lining, polyester knitted fabric-lining), the overlapping width in the stitching area, the number of parallel stitches (single stitch and double stitch), the punching interval and the type of perforations (simple and with eyelets), resulting in nine kinds of samples. Furthermore, the elasticity (Young’s modulus) and lateral contraction (Poisson’s ratio) were calculated during the tensile strength analysis performed on the SATRA STM 466 equipment. Both mechanical parameters are essential to simulate the behaviour of the virtual footwear prototypes in various conditions.
