Membrane Effects in Biaxial Compression Tests

Journal of Geotechnical and Geoenvironmental Engineering, 2009
The effects of the confining membrane in laboratory tests on soil specimens have been the subject of numerous experimental, analytical, and numerical studies over the past half-century. This technical note expands the existing knowledge base by presenting a methodology and the associated results from an experimental study that has quantified the effect

Tests of long plates under biaxial compression

Journal of Constructional Steel Research, 1993
Abstract A plate test rig has been modified to apply biaxial compressive loads to rectangular plates. Attention was paid to defining boundary conditions and ensuring that loadings were correctly measured. Test plates were of 6 mm thick high-yield structural steel, containing residual stresses and initial out-of-flatness. Tests measured the effect of

Comparing compression and biaxial tests for bread dough

Journal of Non-Newtonian Fluid Mechanics, 2013
Abstract Due to the potentially anisotropic microstructure of bread dough, the pre-test deformation produced during the making of the specimens significantly affects the rheological properties of dough, and the resistance to deformation is increased. Some new experimental results for JANZ dough are reported in this paper. Lubricated compression tests

A Fatigue Test Machine for Biaxial Compression of Concrete

Journal of Testing and Evaluation, 1988
Abstract A 980 kN (220 000 lb) capacity test machine has been developed to study the fatigue behavior of concrete under biaxial compression. It features a load bifurcation mechanism and brush-type loading platens. Concrete plates 15.2 by 15.2 by 3.8 cm (6 by 6 by 1.5 in.) can be tested with the two principal stress ratios ranging from 0 (
