Investigation of Geogrid Reinforced Soil Using Biaxial Compression Tests

2013
The principle compound behavior of geogrid reinforced soil is being investigated with large scale laboratory tests and corresponding numerical simulations. With a highly sophisticated testing device developed at RWTH Aachen University, biaxial compression tests of geogrid reinforced soil have been carried out under plane strain conditions with specimen

Investigation of the failure mode of shale rocks in biaxial and triaxial compression tests

International Journal of Rock Mechanics and Mining Sciences, 2015
Abstract High horizontal in-situ stress and weak sedimentary laminated roof rock can severely affect underground coal mine roof stability. These sedimentary rocks possess planes of weakness along the horizontal direction in a mine roof and delaminate easily when acted upon by high lateral stresses.

Path Dependent Biaxial Compressive Testing of an All-Lightweight Aggregate Concrete

ACI Journal Proceedings, 1972
USING 2 IN. CUBICAL SPECIMENS, BIAXIAL COMPRESSION-COMPRESSION STRENGTH ENVELOPES WERE OBTAINED FOR THREE STRENGTHS OF 0.375 IN. (10 MM) MSA ALL-LIGHTWEIGHT AGGREGATE CONCRETE: 2 KSI, 3.5 KSI, AND 5 KSI (140, 245, AND 350 KGF/SQ CM). THE DESIRED STRESS STATE AND THE ELIMINATION OF FRICTION WERE ACHIEVED BY LOADING THE SPECIMENS THROUGH WIRE BRISTLE ...

A simulation study of microstructure evolution inside the shear band in biaxial compression test

International Journal for Numerical and Analytical Methods in Geomechanics, 2011
AbstractWe study the development of microstructure inside the shear band in granular media consisting of elliptical‐shaped particles. Plane strain biaxial compression test was simulated using two‐dimensional distinct element method. The generation of large voids and concentration of excessive particle rotation inside a shear band are found in a quite ...

DYNAMIC BIAXIAL COMPRESSION CARRIED OUT ON HOPKINSON BARS: EXPLORATORY TESTS

2017
L’identification de lois de comportement complexes sur des matériaux nécessite des essais multiaxiaux. Malheureusement, la réalisation de tels essais sur un système de barres de Hopkinson se révèle problématique en raison de la nature uniaxiale de la sollicitation générée par l’impact du projectile sur le système de barres.

Development and Application of Biaxial Compression Test Device for Metallic Materials

2007
The multiaxial testing methods have been used to investigate the mechanical behavior of engineering materials, especially for evaluating yield surfaces and forming limits. Most of the methods employed are a biaxial tension test and a bulge test for sheet material in small strain range, e.g. by [1] and by [2], and a torsion test with tension or internal

Failure Testing Under In-Plane Biaxial Tension and Out-of-Plane Compression

The deformation and failure behavior of 2024 aluminum was investigated under combined in-plane equi-biaxial tension and out-of-plane compression. This loading configuration yields stress states of Lode parameter = −1 and triaxialities ranging from −0.67 to 0.17.
