Analytical modeling flow dynamics of pads by material while tightening shoelaces of shoe upper preform
Keywords:quality of tightening shoelaces, forming, deformation of the material, flow, strain parameters, markers and cells
The paper presents the principles, approaches for the precise study of factors affecting the quality of shoe upper forming. It id proposed a new method for calculating the dynamics of unstable flows using the method of markers and cells that are constructed as finite differences. It is solved the problem to determine the velocity field and the strain attached to them with the boundary conditions with movement of the particles of the material
