The numerical modelling is discussed of plane strain compression tests on sand samples reinforced with geotextile layers. The experimental investigation was carried out on specimens containing either horizontal reinforcements, or reinforcements inclined with respect to the vertical loading direction. Two alternative finite elements approaches, referred to as “inhomogeneous” and “homogeneous”, were adopted for interpreting the tests. The comparison between experimental and numerical results led to some conclusions on the influence of the mechanical properties of the geotextiles, and of their inclination, on the overall behaviour of the reinforced samples.

Abstract
The numerical modelling is discussed of plane strain compression tests on sand samples reinforced with geotextile layers. The experimental investigation was carried out on specimens containing either horizontal reinforcements, or reinforcements inclined with respect to the vertical loading direction. Two alternative finite elements approaches, referred to as “inhomogeneous” and “homogeneous”, were adopted for interpreting the tests. The comparison between experimental and numerical results led to some conclusions on the influence of the mechanical properties of the geotextiles, and of their inclination, on the overall behaviour of the reinforced samples.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
