Dear Mark

Residual stresses have been long known by mine and tunnel engineers as well as petroleum engineers and it directly affects well, mine shaft and tunnel planning especially at great depths due to significant tunnel/well deformation and danger of rock bursts.

A quick Google Scholar search with keywords such as residual rock stresses or in-situ rock stresses should get you started. References may include works like:

Subject: Re: Residual stress in rocks?

Dear Mark,

Residual stress is a real phenomenon, poorly understood in Earth Science but perhaps better understood by material scientists/engineers. It is the stress approaching equilibrium in the interior of a rock or mineral, when neither normal or shear stresses are being transmitted through its surface. Crystal-plastic deformation or phase transitions are potentially responsible for the development of residual stresses in earth materials.

It can be measured directly using synchrotron x-ray radiation. It is possibly amenable to neutron diffraction analysis as well. If you achieve some reasonable results in your research it will be a very interesting result and potentially quite high impact.

For a recent study I recommend;

Chen et al., GEOLOGY, March 2015; v. 43; no. 3; p. 219–222

Also the excellent text book;

Zang & Stephansson, Stress Field of the Earth's Crust, Springer.

I'm actively working on this and am open to discussing collaborations in the field.

Dear All

Do rocks retain a residual stress?

This is a concept I have often heard implied but I had never seen any research that looked to directly test it. I have one rock mechanics paper (Bott, 1970) that used stress gauges in a basalt to suggest the presence of a residual stress (due to volume change during crystallisation I assume but not stated), but am having difficulty in finding more on the topic of residual stress.

Therefore, I am seeking research papers, experiments, and options from a geological and rock mechanics perspective on the concept of residual stress in rocks due to factors such as lithofication/burial, brittle and ductile deformation, volume change during solidification of magma, and/or mechanical loading (intact rock testing etc.).

References and/or reprint PDF of hard to find texts would be greatly appreciated and best sent off list to: [log in to unmask]
