- Abstract
A dynamic model of the needle-punching process was developed in which the nonwoven material (NM) is modeled by an isotropic, deformable, continuous medium. The model allows assigning the NM elastic and plastic properties at each point of the sample. The distribution fields of the characteristics of elastic, plastic, and total deformation and stress over the entire volume of the sample were obtained as a result of modeling using the finite element method. The dependence of the characteristics of deformation on the density of the material and the damping coefficient was investigated. The model allows finding the regions and times during needle-punching when the NM is subject to the greatest stresses and strains. Modeling the process in relative units allows taking into account that the characteristics found are common to different types of NM.
