Mechanical behaviour of compacted decomposed granite soil
The purpose of this research was to determine the mechanical behaviour of decomposed granite soil, especially when it is used as a construction material. The soil tested was a completely weathered granite soil (grade V) taken from Seoul, Korea and was a well graded silty sand and gravel. Triaxial …

The mechanical behaviour of polyethylene pipe systems
… and work was undertaken to fully characterise mechanical performance in terms of internal pressure loadings. Butt-welded test specimens comprising pipe lengths and fittings were subjected to both static and fluctuating conditions at 80°C, at pressures resulting in brittle fractures (below the …

Mechanical behaviour of adhesive anchors installed in concrete
… thesis presents the main characteristics of the mechanical behaviour of adhesive anchors installed in concrete. They are the mechanisms of failure, the relationship between applied pull-out'loadand slip of the anchor and the stresses and strains in each of the three components …

Effect of microstructure on mechanical behaviour of arterial tissue
… the relationship between microstructure and mechanical, including fracture behaviour of arterial tissue. Unnotched and notched mechanical tests were performed on tissue samples from aneurysm-affected aortas. Mechanical parameters of ultimate material strength and extreme extensibility were …

Modelling the mechanical behaviour of the interface between prosthesis and bone
… cement-bone interface are well documented the behaviour and load transfer across the interface at the trabecular level has been largely neglected. In addition, modelling of the cement-bone interface has mostly been limited to evaluation at the continuum level. In the following study, two …

Coupling of mechanical behaviour and water retention behaviour in unsaturated soils
Previous research has shown coupling of mechanical behaviour and water retention behaviour in unsaturated soils at a constitutive level, with degree of saturation (in addition to suction) influencing mechanical behaviour and volumetric strains influencing water retention behaviour. An innovative …

The mechanical behaviour of soft clays under vibration loading from vehicle traffic
… increased the need for advanced studies on the mechanical behavior of soft clays. One of the most important aspects of soft clay behaviour is the time dependent deformation characteristics. The behavioral characteristics of soft clays suggest that an overstress type soil model is suitable for …

Material properties and mechanical behaviour of large-scale additively manufactured multi-layered steels
… interface between the two materials. Deformation behaviour was analyzed by the use of two-dimensional digital image correlation. Nonhomogeneous strains and Lüders banding within the mild steel directly adjacent to the SS-MS interface were observed. There is a clear increase in strength close to …

The influence of the microstructural shape on the mechanical behaviour of interpenetrating phase composites
… effect of phase shape on the elastic and plastic behaviour. A review of previous research showed that investigations had linked phase shape to the elastic and plastic behaviour of various inclusion reinforced composites, but that no similar work had been completed for IPCs. To study the complex …

CHARACTERISATION OF THE MECHANICAL BEHAVIOUR OF NETWORKS AND WOVEN FABRICS WITH A DISCRETE HOMOGENIZATION MODEL
… progress in the development of new materials for mechanical related applications. New generations of composites have been developed, that can offer advantages over the unidirectional fibre-reinforced mats commonly used then materials take the name of woven fabrics. The behaviour of this material …
