“…The material model MAT MICROMECHANICS DRT FABRIC was the best suited to capture the load-displacement trend of the experimental bias-extension test. 20 To estimate the shear modulus of a continuous yarn model for FE modeling of ballistic impact events, a reverse engineering method was presented for continuous yarn models of different materials. 21 The bursting behavior of the spun-bonded nonwovens with different MPUAs was simulated based on the damage and the layered structure using the FEM.…”

Arimatsu Narumi Shibori (thread-tying), which is a traditional craft, has a history of more than 400 years and has been handed down to artisans in Japan. Recently, the shortage of successors to artisans has emphasized the maintenance of this thread-tying technique. To achieve this, Arimatsu Narumi Shibori needs to be elucidated based on scientific knowledge using numerical analysis techniques, which has not been achieved so far. In this technique, the fabric is complexly deformed, and complex wrinkles are formed in it. One possible approach for modeling this fabric is the use of a shell element that does not have an element volume. As the tensile and bending stiffnesses of the shell element are evaluated using a single Young’s modulus, the bending stiffness increases with the tensile stiffness. Therefore, unlike the deformation achieved by the actual fabric-tying, this fabric analysis model cannot achieve large deformation of the fabric. In this study, a tying analysis method is proposed to elucidate Arimatsu Narumi Shibori. In this method, the fabric is modeled using three layers of shell elements to reproduce the fabric behavior. The material properties of the three-layer structure are presented based on the tensile test, the bending test and the friction test. Using the proposed method, we could visualize the stress distribution and wrinkles in the fabric-tying and elucidate its breaking condition.

“…Experimental tests were performed by the authors in previous works [20,35,38,39], where standard coupon test were conducted to characterize the mechanical response of the material, summarized in Table 1. From the tests, it emerged that the tensile behavior of the material is characterized by high elongation to failure and the failure is dominated by delamination.…”
