Measuring and modelling deformation during the Dabbahu (Afar) rifting episode [PDF]

open access: yes, 2010
In September 2005, a 60-km-long dyke intruded the Dabbahu segment of the Nubia-Arabia plate boundary (Afar, Ethiopia), marking the beginning of an ongoing rifting episode.

The creep behavior of simple structures with a stress range-dependent constitutive model [PDF]

open access: yes, 2012
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

Correlation of microseismic and chemical properties of brittle deformation in Locharbriggs sandstone [PDF]

open access: yes, 2003
The time-dependent properties of ceramic materials such as rocks depend both on preexisting cracks and chemical properties acting at their tips. We have examined the direct effect of chemical processes on the growth of a crack population by carrying out ...

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

open access: yes, 2013
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

open access: yes, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Evaluation of safety performance of extremely high slab-faced gravel dams

open access: yesYantu gongcheng xuebao, 2017
The structural safety performance of Dashixia concrete face gravel dam (CFGD), an extremely high CFGD in Xinjiang, is studied based on the large-scale triaxial experiments on dam materials and the detailed finite element method-based numerical analyses ...

Research on On-line Monitoring of Lateral Coal Stress and Deformation and Reasonable Delay Time of Gob-side Entry Driving in Deep Mine

open access: yesMeikuang Anquan, 2020
The determination of reasonable delaying roadway driving time is critical to fundamentally avoid the impact of mining roadway on the working face. Based on the geological and mining technical conditions of 7432 working face of Kongzhuang Coal Mine, the ...

Analysis of strength-deformation behavior of coral sand with different densities and stress levels

open access: yesShuili Shuiyun Gongcheng Xuebao, 2020
In order to study the influences of density and stress level on the strength and deformation characteristics of the coral sand, a series of triaxial consolidation drained shear tests with different densities and stress levels are carried out using a ...

A size-dependent functionally graded sinusoidal plate model based on a modified couple stress theory [PDF]

open access: yes, 2013
A size-dependent model for bending and free vibration of functionally graded plate is developed based on the modified couple stress theory and sinusoidal shear deformation theory.

Neotectonic deformation features in plio-pleistocene coastal aeolianites: palaeoseismology and earthquake hazard implications for the Southern Cape, South Africa [PDF]

open access: yes, 2013
Deformation features within Plio-Pleistocene Bredasdorp Group coastal aeolianites within the Southern Cape, South Africa, have been studied to resolve the neotectonic history of the region, estimate the recent to current upper-crustal stress field, and ...
