Kaiser Effect in Rock Salt

Journal of Mining Science, 2002
Using the results of experiments with rock salt samples under various loading regimes as an example, the regularities of the Kaiser effect formation and manifestation in rocks with plastic properties are investigated.

The Kaiser Effect in Rocks: Principles and Stress Estimation Techniques

International Journal of Rock Mechanics and Minings Sciences, 2003
Irreversible deformation of rocks is accompanied by the Kaiser effect involving acoustic emission (AE). AE activity increases dramatically as soon as the largest previously experienced stress level is exceeded, similar to strain hardening in ductile materials. The Kaiser effect can be considered as a basis for stress measurements in rocks.

Experimental verification of the Kaiser effect in rocks

Rock Mechanics and Rock Engineering, 1993
The Kaiser effect is a measure of damage developed in rock. It was investigated using 61 core specimens of eight types of rocks under uniaxial cyclic loading.

General theory of the Kaiser effect

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1993
Abstract A theory for the generalized Kaiser effect is discussed. Using the concept of a damage surface, the one-dimensional Kaiser effect is extended to a general stress state. Comparisons between the theory and experimental data show agreement in the predicted and observed properties of the Kaiser effect.

Effective Psychotherapy: The Contribution of Hellmuth Kaiser.

Archives of General Psychiatry, 1966
This is an interesting and thought-provoking book. It consists of the only three papers on psychotherapy written in English by Hellmuth Kaiser, a lay analyst with a PhD in mathematics and philosophy from Munich. The two shorter papers have been published previously in Psychiatry , but the longer paper, his major contribution, has never before been ...

Kaiser Effect in Rocks Undergone Polyaxial Loading

Journal of Mining Science, 2002
The basic regularities are considered for manifesting the Kaiser effect in various regimes of polyaxial loading, which is of great importance for developing the methods of stress measurement in rocks. The correspondence between the results of experimental and theoretical investigations is shown.

The Kaiser Effect under Multiaxial Nonproportional Compression of Sandstone

Doklady Physics, 2020
The regularities of deformation and fracture of sandstone under nonproportional biaxial and triaxial cyclic compression accompanied by the rotation of the Lame ellipsoid and in situ continuous detection of acoustic emission are investigated experimentally on the “Triaxial Independent Loading Test System” at the Ishlinskii Institute for Problems in ...

Detection of Kaiser Effect in Marbles under Brazilian Tests

Advanced Materials Research, 2010
Kaiser effect was noticed while submitting marble samples to Brazilian tests. An automatic data acquisition system was applied by means of analog to digital conversion, upon recording analog signals of stress, strain and acoustic emission (AE) emitted from Portuguese marble specimens under diametrical loadings in different loading cycles.
