METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM CONTAINING COMPUTER PROGRAM IMITATING WOVEN TEXTILE BEHAVIOUR INTERWOVEN AT THREAD LEVEL Russian patent published in 2019 - IPC G06F17/50 

FIELD: calculating; counting.

SUBSTANCE: invention relates to imitation of fabric woven behaviour at suture level. Method includes obtaining distribution of warp threads (1), weft threads (2) and thread crossing units (3); description of each thread intersection unit (3) using 3D position coordinate (x) and two sliding coordinates - sliding coordinate (u) and sliding coordinate (v) of warp thread (1) and weft thread (2), respectively; measuring forces in each thread intersection unit (3) based on the power model, where said forces are measured in 3D position coordinate (x) and in sliding coordinates (u, v); and calculating motion at each thread intersection node (3) using motion equations obtained using Lagrange-Euler equations and subjected to numerical integration over time, wherein said equations of motion take into account mass density (ρ), distributed uniformly along threads, as well as measured forces and boundary conditions.

EFFECT: technical result consists in providing simulation of fabric woven behaviour at the level of the high-resolution thread and short computation time.
