... digital image correlation ( DIC ). Its accuracy is evaluated using in-isolation tensile tests conducted on two types of high-density polyethylene ( HDPE ) geomembranes and three types of nonwoven polypropylene ( PP ) geotextiles. Quantitative comparisons with existing methods are made using error metrics...

...T. Yardimci; E. Guler; B. F. Tanyu An in-soil tensile test apparatus was developed to investigate the in-soil load-strain relationships of geosynthetics. The strain-controlled tests were performed to evaluate the influence of soil type, confinement pressure and vertical spacing on the reinforcement...

...T. Krahn; J. Blatz; M. Alfaro; R. J. Bathurst ABSTRACT This paper presents results of large-scale direct shear testing of six interfaces with materials used to construct sandbag dykes for flood protection structures. Two additional test series using intact sandbags were also conducted to examine...

...S.R. Boyle; M. Gallagher; R.D. Holtz In-isolation and in-soil tests were performed on four woven and two nonwoven geotextiles to investigate the effect of strain rate, specimen length, and confinement in soil on the measured strength characteristics. It was determined that woven geotextiles...
