The high plasticity of metallic glasses is highly desirable for a wide range of novel engineering applications. However, the physical origin of the ductile/brittle behaviour of metallic glasses with various compositions and thermal histories has not been fully clarified. Here we have found that metallic glasses with compositions at or near intermetallic compounds, in contrast to the ones at or ...

Mode I fracture toughness (KIC) and rock brittleness are important properties that influence many engineering applications. Due to the difficulties in determining KIC experimentally, previous studies have investigated relationship between indices. However, only indices (based on strength parameters) obtained from Chevron Bend Short Rod test methods were considered. In this paper, regression ana...

[Learning] Classifier systems are a kind of rule-based system with general mechanisms for processing rules in parallel, for adaptive generation of new rules, and for testing the effectiveness of existing rules. These mechanisms make possible performance and learning without the " brittleness " characteristic of most expert systems in AI.

Brittleness is important in the evaluation of fracturing ability shale reservoir and has a significant impact on gas exploration development. This paper discusses characteristics controlling factors brittleness continental Da’anzhai Member Ziliujing Formation Lower Jurassic age northeast Sichuan Basin. Continental lithofacies their associations were grouped into four main rock types: clayey sha...

Introduction Elemental beryllium is a steel gray appearing alkaline earth metal with properties like brittleness and high rigidity being the lightest among metals. The majority of beryllium is found in minerals and soils rather than in its elemental form. Beryllium is found in about 30 different mineral species like different compounds including aluminium e.g. Beryl (beryllium aluminium silicate).

Abstract The influence of stress anisotropy ( K ) (i.e. the ratio between effective horizontal and vertical stresses) on shear behaviour soils has received significant attention in past studies, but how its depends different values plasticity index (PI) not been properly quantified. In this study, results a series undrained triaxial tests anisotropically consolidated soil at are reported , toge...
