Apparatus for Cyclic Stress Path Testing
Geotechnical Testing Journal, 1983Abstract A simple change in the conventional cyclic triaxial cell was made to carry out constant mean stress tests on dry Ottawa sand. Test results show that stress-strain characteristics under cyclic loading conditions are significantly affected by the imposed stress path.

Abstract This chapter is divided into two main sections where different aspects of the interaction between morphology and stress assignment are discussed. Section 7.2 is concerned with cyclic application of the Main Stress Rule (MSR), while the subject of Section 7.3 wil1 be stress demotion in compounds.

Effect of Cyclic Stress and Temperature on Residual Stress Relaxation
1989Residual stress relaxation has been studied on shot peened medimum carbon steel under pyolio stress lover than the fatigue limit and vith thermal effect. The different effeots of oyolio stress and temperature on residual stress relaxation are discussed.

Continuous and cyclic stress relaxation in aluminium
Materials Science and Engineering: A, 1991Abstract The stress relaxation behaviour of aluminium (99.99%) was investigated at three temperatures (295, 363 and 433 K). In addition to the customary experimental procedure, by which the total strain of the specimen is held constant during the test, the influence of cyclic unloading on stress relaxation behaviour was examined.

The hardening and softening of metals by cyclic stressing
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1957Abstract Metals subjected to alternating tensile and compressive stresses give characteristic stress-strain relationships. Recent studies have shown that the Bauschinger effect in single crystals and the hardening that is observed during cycling at constant strain amplitude are closely related to the modes of deformation of single ...

Residual stresses in cyclic powder compaction
Journal of Materials Processing Technology, 1992Abstract The behavior of a powder during isostatic compaction is simulated by a hollow sphere model. A flexible one-dimensional finite element analysis is presented for a hypoelastic and strain-hardening plastic behavior of the matrix at finite strains.

Effect of cyclic stress on Terfenol-D
IEEE Transactions on Magnetics, 1996A rod of grain oriented Terfenol-D has been subjected to cyclic uniaxial stress of /spl plusmn/100 MPa about a mean preload of /spl sim/120 MPa applied along the grain growth axis. The magnetostrictive strain and d-coefficient measured under uniaxial preload and quasi static magnetic fields are shown to increase after the initial 10/sup 6/ cycles of ...

Behavior of Proppants Under Cyclic Stress
SPE Hydraulic Fracturing Technology Conference, 2007Abstract Size distribution of proppants is one factor that determines fracture conductivity. Sufficient closure stress can cause mechanical failure of proppants changing the size distribution and altering the bulk properties of the pack.

This chapter is mainly concerned with the specification of stress-strain relationships under monotonic and cyclic loading. Various factors such as rate of loading, environment and temperature affect the stress-strain relationship. It will be seen that the cyclic stress-strain curve differs from that of the monotonic curve in several aspects.

Cyclic Stress-Strain Characteristics of Clay
Journal of the Soil Mechanics and Foundations Division, 1968The decreases in moduli and increases in yield strain occurring during cyclic loading of sensitive clay under simple shear conditions are examined. The loading conditions are representative of those associated with the upward propagation of a seismic shear wave through a large mass of soil; i.e., the strain is completely reversed during each cycle at ...
