Puncture resistance of pre-strained geotextiles and its relation to uniaxial tensile strain at failure

Abstract The principal focus of this study is the puncture resistance of geotextiles under uniform radial pre-strain. A test frame which can apply preset radial strain and measure puncture resistance of geotextiles has been developed. A number of commercially available woven and nonwoven geotextile materials have been evaluated for puncture resistance while held under a preset radial strain. The test results show lower failure strain in puncture if the test sample is pre-strained. The failure strain measured in wide width tensile tests are much higher than calculated strains in puncture.
