Mechanical Properties Of Three-dimensional Network Computer-aided Analysis

Several properties of three-dimensional net(a new type ofgeotxtile ) were studied.These properties are mechanical properties,burst properties,their relations and waterproof erosion properties.This article derives the equation of the materialand cocludes the factors deforming the three-dimensional net during extensional motion by applying the finite element analysis in the physical non-linear features of the materials to simulate and studymechanical properties of the three-dimensional net. It providesfeasibilities to study other non-woven products.This article derives regularties and provides grounds in practical engineering application through studying the relation between the mechanical properties and burst properties. It proves that the three-dimensional net has effective functions of waterproof erosion and earth-fixing by studying its properties of protecting slopes from streams eroding.
