INFORMATION TECHNOLOGIES IN DESIGN OF THE GEOTEXTILES BY FINITE ELEMENT ANALYSIS

Abstract

The motto of the conference "Let's build the future through learning innovation" is the best way to formulate the proper development strategy for higher education. First of all this motto is valid for engineering higher education. When training specialists, particularly in the period of economic distress, it is necessary to focus on the most promising the so-called "critical technologies" considering technological, economic and environmental components in the aggregate.Production and application of technical textiles and fibre-reinforced composites have a high importance for technological breakthroughs in many industries. In this direction the study was carried out. A technical textile as the most dynamically developing innovative textiles requires new approaches in the designing. Geotextiles as a significant part of technical textiles are different depending on application, soil composition, raw materials used the structure and usage conditions. Developed a theoretical description of the interaction of geotextiles with the soil, the method of its calculation by numerical methods which allows to predict (simulate) the permeability properties with IT. This approach in the design of newly materials will be useful for students and researchers from theoretical, methodological and instrumental perspectives. The research substantiates the use of warp-knitted mesh structures geotextiles from the flax yarn for prevention of surface soil erosion complex relief and slope. The analytical analysis of fluid filtration across textile geomaterial multilayer structure which is laid inside a soil under overlay load is done. The technique has based on finite element method (FEM) makes it possible to forecast of geotextiles permeability properties which are necessary for granulated solids reinforcement. The theoretical analysis of the transport properties of porous structures depending on the degree of contraction by external loads using finite elements method was done. Methods for calculating in MatLab the moisture permeability of multilayer porous materials depending on the contraction degree in relation to geotextiles were developed.
