Five out of six functioning creepmeters on southern California faults recorded slip triggered at the time of some or all of the three largest events of the 1992 Landers earthquake sequence. Digital creep data indicate that dextral slip was triggered within 1 min of each mainshock and that maximum slip velocities occurred 2 to 3 min later. The duration of triggered slip events ranged from a few ...

The conditions for localization in a material described by a non-local damage-based constitutive relation coupled with a Kelvin type creep relation are derived in a closed form. The inception of a localized mode is considered as a bifurcation into Preprint submitted to Elsevier Science 15 February 2006 a harmonic mode. The criterion of bifurcation is reduced to the classical form of singularity...

Underground rock engineering often encounters long-term cyclic loading and unloading. Under the influence of this effect, mechanical characteristics rocks will inevitably change, which affect stability safety underground engineering. Therefore, it is necessary to study fatigue under a certain period action. With an RDL series electronic creep relaxation testing machine, unloading tests sandston...

Abstract—Rockfills are widely used in civil engineering, such as dams, railways, and airport foundations in mountain areas. A significant long-term post-construction settlement may affect the serviceability or even the safety of rockfill infrastructures. The creep behavior of rockfills is influenced by a number of factors, such as particle size, strength and shape, water condition and stress le...

This work deals with an experimental and numerical approach to determining the differed behavior of compressed wood elements subjected creep loading. An protocol is associated a mechanical model, whose purpose isolate effects from those shrinkage-swelling, while allowing for long duration test be conducted. The based on compression applied five wooden columns disposed in climatic room one year....

The construction of the future is moving in direction environmentally friendly materials and use various types industrial byproducts wastes. blast furnace slag (BFS) for production concrete one those alternatives. In this study, pastes concretes based on high-MgO BFS were alkali activated with 10% by weight sodium carbonate, silicate, a combination both. Heat treatment laboratory curing applied...

Utilizing underground coal gasification cavities for carbon capture and sequestration provides a potentially economic sustainable solution to vexing environmental energy problem. The thermal influence on creep properties long-term permeability evolution around the chamber is key issue in UCG-CCS operation containing fugitive emissions. We complete multi-step loading unloading tests with measure...
