Adhesive friction at the contact between rough surfaces using n-point asperity model
The paper describes a theoretical study of adhesive friction at elastic–plastic contact of rough surfaces based on n-point asperity model. Well defined adhesion index and plasticity index are used to study the prospective situations arising out of ...

Temperature effect on the mechanical behavior of shale: Implication for shale gas production
Deformational shale attributes such as fracture toughness, tensile strength, and axial point load strength (PLS) index under elevated temperatures are crucial for the petroleum and gas industries. Here, an attempt has been made to investigate the thermal

The creep behavior of simple structures with a stress range-dependent constitutive model [PDF]
High temperature design remains an issue for many components in a variety of industries. Although finite element analysis for creep is now an accessible tool, most analyses outside the research domain use long standing and very simple constitutive models

Characterization of rock material by point load strength index test and direct cut
The objective of this work is to establish a relationship between the cutting time in rocks, determining a speed and the point load strength index test, Is (50), to characterize the rock in terms of resistance and avoid sending samples to laboratories. As a first stage, on andesite samples, 5 x 5 x 10 cm test tubes were made. After the elaboration they

Observer-biased bearing condition monitoring: from fault detection to multi-fault classification [PDF]
Bearings are simultaneously a fundamental component and one of the principal causes of failure in rotary machinery. The work focuses on the employment of fuzzy clustering for bearing condition monitoring, i.e., fault detection and classification.
