Problems of Multiscale Brittleness Estimation for Hydrocarbon Reservoir Exploration and Development

open access: yesApplied Sciences, 2022
The study is focused on the problem of using geophysical data to estimate brittleness of rock masses for the needs of petroleum industry. Three main developed ways to estimate brittleness—mineral-based, log-based, and elastic-based brittleness indices ...

Application of Soft Computing Techniques to Estimate Cutter Life Index Using Mechanical Properties of Rocks

open access: yesApplied Sciences, 2022
The wear of cutting tools is critical for any engineering applications dealing with mechanical rock excavations, as it directly affects the cost and time of project completion as well as the utilization rate of excavators in various rock masses.

Nature of the Brittleness of Metals

open access: yesУспехи физики металлов, 2022
The brittleness of material is considered as a specific manifestation of mechanical behaviour under load, which appears in the instability of the strength characteristic value under conditions of non-uniformity of the stress–strain state (SSS).

Impact of Wood Moisture Content on Structural Integrity of Wood Under Dynamic Loads

open access: yesDrvna Industrija, 2023
The majority of mechanical wood properties are negatively affected by wood moisture within the hygroscopic range, disregarding the stress relaxation of wood at very low moisture contents (MC).

Multidisciplinary Characterization of Unconventional Reservoirs Based on Correlation of Well and Seismic Data

open access: yesEnergies, 2020
Combinatorial analysis of key petrophysical parameters can provide valuable information about subsurface hydrocarbon reservoirs. This is particularly important for reservoirs with unconventional rock formations that, due to the low permeability, need to ...

DENTAL CERAMICS - MECHANICAL PROPERTIES

open access: yesČeská Stomatologie a Praktické Zubní Lékařství, 2022
Introduction, aim: Ceramic is a mixture of inorganic non-metallic materials. The history of the ceramic is dated since Paleolithic age. It is used, for example for production of jewelry, dishes, the construction industry, sculpturing and of course in ...

Brittle asthma [PDF]

open access: yesThorax, 1998
We believe that the asthma phenotypes we have defined as types 1 and 2 brittle asthma appear to be defined subgroups of asthma. For example, we have characterised patients with type 1 brittle asthma, as defined in this review, on the basis of peak flow variability and treatment and these patients remain a separate group when assessed by other means ...

Numerical Modeling of a Punch Penetration Test Using the Discrete Element Method

open access: yesSlovak Journal of Civil Engineering, 2020
Understanding the brittleness of rock has a crucial importance in rock engineering applications such as the mechanical excavation of rock. In this study, numerical modeling of a punch penetration test is performed using the Discrete Element Method (DEM).
