Computer Simulation of Mechanical Properties of Nonwoven Geotextiles in Soil-Fabric Interaction

摘要

The mechanical behavior of nonworen getoextiles in soil-fabric interaction is in- vestigated through laboratory experiments and theoretical analysis. A computer model is presented to simulate geotextile performance in pullout tests. The model parameters are based on single fiber properties and the fiber orientation function. A new finite element method is used to calculate numeral solutions of stress and strain distribution in different regions developed in the fabric during the pullout test.
