Deformation

A retaining wall constructed on expansive soil can be subjected to lateral swelling pressures due to soil swelling, which may cause a significant horizontal deformation and bending of the retaining wall. In Australia, it is generally assumed that the backfill behind a retaining wall is non-expansive material. Therefore lateral swelling pressures induced by expansive soils are ignored in routine design.

The proposed research aims to investigate the influences of temperature on the water retention behaviour of deformable unsaturated soil. Volume change caused by temperature variation will be taken into consideration. This research will produce a better understanding and interpretation of thermal effects on SWCCs by providing experimental results for deformable unsaturated soils.

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matrix composites (MMCs). Microstructure analysis on the individual sample before and after loading was performed under scanning electron microscopy. The small particles of 2 µm in size have exhibited strong interfacial bonding with the matrix.

In this paper, the severe plastic deformation method (SPD) known as constrained groove pressing (CGP) was applied to produce ultrafine-grained microstructure in IF steel sheets. In the CGP technique, samples are subjected to repetitive shear deformation under the plane strain deformation condition using the constrained grooved and flat dies.

The concept of a deformable body point is taken in the form of a continuum point and an elementary volume connected with it. The continuum point determines the spatial position of the deformable body point, and the elementary volume is the carrier of its material properties and stress-strain state characteristics.
