Structural geology uses micro- and meso-scale structures found in the rocks to elaborate tools and methods enabling to identify structures too large to be directly observed, although satellite imagery now may help in this task. Structural Geology vs. Structural Geology: an introduction to geometrical techniques 3rd ed.

Many students have a difficult time realizing that rocks can bend or break. They also may have difficulty imagining the forces necessary to fold or fault rocks or comprehending that the seemingly constant Earth can change dramatically over time. This is especially true of students who live in tectonically stable areas. If students are to understand the basics of stress and strain, they must overcome this barrier since it will be difficult to examine the causes and conditions of deformation if students cannot comprehend deformation.

It seems that you're in Germany. We have a dedicated site for Germany. This is an elementary book on stress and strain theory for geologists. This view is shared by most specialists in structural geology, but it is not yet reflected in typical geology curricula. Undergraduates are still traditionally given just a few lectures on mechanical fundamentals, and there is rarely any systematic lecturing on this subject at the graduate level. The long-term remedy for this is to introduce courses in continuum mechanics and material behavior as routine parts of the undergraduate curriculum.

Structural Geology

Plate collisions and the accumulated weight of overlying rocks exert forces on rocks at depth. While the size of the force is important, it also matters whether the force is distributed over a wide region, or tightly focused on a small area. The same force will have a greater effect when acting over a small area than when acting over a larger area. If you have ever used snowshoes to walk across a snow bank without sinking in, you have taken advantage of the effects of distributing force your mass acted upon by gravity over a wider area the area of your snowshoes rather than the soles of your boots. Stress is force adjusted for the area over which it is distributed. Strain is the change in shape that happens when rocks are deformed by stress. Stresses fall into two categories: normal stress acts at right angles to a surface, and shear stress acts parallel to a surface Figure

Stress and Strain

Writing papers with an emphasis on structural geology and tectonics: advices and warnings. E-mail: haakon. The objective of this short paper was to provide some advice on how to write a geoscience paper of international standard and to warn against some common pitfalls.

Elastic Strain

Соши прочитала снова: - …Искусственно произведенный, обогащенный нейтронами изотоп урана с атомным весом 238. - Двести тридцать восемь? - воскликнула Сьюзан.  - Разве мы не знаем, что в хиросимской бомбе был другой изотоп урана. Все вокруг недоуменно переглянулись. Соши лихорадочно прогоняла текст на мониторе в обратном направлений и наконец нашла то, что искала. - Да. Здесь говорится о другом изотопе урана.

 - Могу я чем-нибудь тебе помочь, прежде чем уйду. Он посмотрел на нее умоляюще и покрутил затекшей шеей. - У меня затекли плечи. Мидж не поддалась. - Прими аспирин. - Не помассируешь мне спину? - Он надулся.

Пытаясь подняться на ноги, Стратмор в ужасе смотрел на предмет, зажатый в его пальцах: это была рука Чатрукьяна, обломившаяся в локтевом суставе. Наверху Сьюзан ждала возвращения коммандера, сидя на диване в Третьем узле словно парализованная. Она не могла понять, что задержало его так надолго. У ее ног лежало тело Хейла. Прошло еще несколько минут.

13.1 Stress and Strain

Через десять минут Беккер уже сидел в буфете АНБ, жуя сдобную булку и запивая ее клюквенным соком, в обществе очаровательной руководительницы Отделения криптографии АНБ. Ему сразу же стало ясно, что высокое положение в тридцать восемь лет в АНБ нельзя получить за красивые глаза: Сьюзан Флетчер оказалась одной из умнейших женщин, каких ему только доводилось встречать.
