Soil Dynamics and Earthquake Engineering, 2020
Abstract The main research work of this paper is based on the Discrete Element Method (DEM) and completed by the platform of particle flow software PFC2D. A numerical calculation model is established based on the motion equation and the force equation between soil particles which can consider the interparticle rolling resistance and particle shape ...

Strength of Materials, 1975
1. We have created a new method of studying the deformation and rupture resistance of commercial glasses and sitals under conditions of biaxial compression (largely eliminating the effect of high contact stresses on the resultant strength and elasticity characteristics) by gluing the ends of the samples into depressions in the metallic bearings with

A simulation study of microstructure evolution inside the shear band in biaxial compression test
International Journal for Numerical and Analytical Methods in Geomechanics, 2011AbstractWe 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 ...

Path Dependent Biaxial Compressive Testing of an All-Lightweight Aggregate Concrete
ACI Journal Proceedings, 1972USING 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 ...

Investigation of Geogrid Reinforced Soil Using Biaxial Compression Tests
2013The 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

Development and Application of Biaxial Compression Test Device for Metallic Materials
2007The 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.Nathan Spulak +3 more

Development of an experimental facility for biaxial compressive testing of fiber composite materials
1991The purpose of this study was the development of a testing facility and test specimen for the characterization of laminated composites under biaxial compressive stress states. A biaxial testing facility capable of applying almost arbitrary stress paths in the in-plane compressive stress regime, to circular cylindrical test specimens, was designed ...

DYNAMIC BIAXIAL COMPRESSION CARRIED OUT ON HOPKINSON BARS: EXPLORATORY TESTS
2017L’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.
