Cyclic mobility following plastic strain accumulation in sand

Géotechnique Letters, 2023
Hybrid failure modes/mechanisms under non-symmetrical cyclic loading (partial stress reversal) have received little attention. This paper presents data from cyclic undrained triaxial tests of sand, with initial static shear stress, to investigate a hybrid failure mechanism that controls the behaviour of dilative sand in a narrow range of non-symmetric

Mobility in granular materials upon cyclic loading

Granular Matter, 2018
We investigate the ability to move of large objects—referred to as intruders—embedded in a granular material and subjected to cyclic loadings. A discrete element method is used to simulate the dynamics response of intruders subjected to a vertical uplift cyclic force, exploring a wide range of loading magnitudes and frequencies.

Molecular mobility in polymers under cyclic loading

Polymer Mechanics, 1974
Using the NMR method the authors have investigated thermal molecular movement in polymers under the conditions of fatigue tests. They have found that the increase in molecular mobility under cyclic loading (cycle frequency 1–10 Hz) is due only to general self-heating of the polymer.

Liquefaction, Cyclic Mobility, and Failure of Silt

Journal of Geotechnical and Geoenvironmental Engineering, 2006
It is known that the mechanical properties of low-plasticity silt are similar to those of sand, and yet silts are frequently used as coastal reclamation materials in many cities and industrial areas and will thus be susceptible to liquefaction. Samples of a low-plasticity silt have been tested under monotonic and cyclic loading under isotropic and ...

Cyclic ADP-Ribose: Metabolism and Calcium Mobilizing Function

1994
Publisher Summary This chapter describes the discovery of cyclic adenosine diphosphate–ribose (cADPR) as a novel endogenous Ca 2+ -mobilizing agent, and the way by which it fulfills most of the criteria necessary for it to be considered a second messenger. The enzymatic pathways for the synthesis and degradation of the metabolite are also summarized.

Cyclical Dimensions of Labour Mobility after EU Enlargement [PDF]

, 2009
This paper explores the influence of the economic cycle on labour mobility within the EU, focusing on the likely impact of the present economic crisis. To do so, we use an econometrically calibrated simulation and a case study of Ireland. We find that, in the short run, the crisis is likely to lead to a somewhat lower stock of migrants from the new ...

Passive Earth Pressure Mobilization during Cyclic Loading

Journal of Geotechnical and Geoenvironmental Engineering, 2006
The passive resistance measured in a series of full-scale tests on a pile cap is compared with existing theories. Four different soils were selected as backfill in front of the pile cap and the load-deflection relationships under cyclic loading were investigated.

N.m.r. studies of internal mobility in a cyclic tetrapeptide

International Journal of Peptide and Protein Research, 1989
The conformation of cyclo(D‐Phe‐D‐Pro‐Ala‐Pro) is reported. Measurements of spin‐lattice relaxation in the rotating frame indicate that this peptide is conformationally less mobile on the microsecond time scale than larger cyclic peptides previously studied.
