The simulation of the fabric materials behavior on the solid plane—bounded object's surface is considered in the paper. The fabric is represented as a discrete model that can virtually to reproduce real material's properties with high accuracy. The item outline (pattern) is used as an initial data to construct item grid model. Commonly, that outline has the form of any polygon. The grid has to be uniform with square-shaped cells so the active forces occurring in the simulating product were brought in modulus and direction to the forces of the real material that occurs with its deformation. Methods for experimental investigation of the fabric deformation properties are described. Expressions for the strain energy that occurs between the fabric discrete model particles are presented. These expressions take into account experimental data. For simulation the physical methods have been used, namely, the particle method. To solve the differential equation system the leapfrog scheme has to be used. To describe the developed parallel processing algorithm for paralleling the calculations on the central processing unit both for shared-memory systems and for distributed memory systems are presented. Implementation method of parallel computing on graphics processor is presented. The results of numerical experiments for described parallel processing algorithms are provided. Also, the fitting on the dress form of the cotton fabric base construction results are shown. The tension areas of the material are highlighted.
