Rock brittleness indices and their applications to different fields of rock engineering:A review

Brittleness is an important parameter controlling the mechanical behavior and failure characteristics of rocks under loading and unloading conditions,such as fracability,cutability,drillability and rockburst proneness.As such,it is of high practical value to correctly evaluate rock brittleness.However,the definition and measurement method of rock brittleness have been very diverse and not yet been standardized.In this paper,the definitions of rock brittleness are firstly reviewed,and several representative definitions of rock brittleness are identified and briefly discussed.The development and role of rock brittleness in different fields of rock engineering are also studied.Eighty brittleness indices publicly available in rock mechanics literature are compiled,and the measurement method,applicability and limitations of some indices are discussed.The results show that(1)the large number of brittleness indices and brittleness definitions is attributed to the different foci on the rock behavior when it breaks;(2)indices developed in one field usually are not directly applicable to other fields;and(3)the term“brittleness”is sometimes misused,and many empirically-obtained brittleness indices,which lack theoretical basis,fail to truly reflect rock brittleness.On the basis of this review,three measurement methods are identified,i.e.(1)elastic deformation before fracture,(2)shape of post-peak stressestrain curves,and(3)methods based on fracture mechanics theory,which have the potential to be further refined and unified to become the standard measurement methods of rock brittleness.It is highly beneficial for the rock mechanics community to develop a robust definition of rock brittleness.This study will undoubtedly provide a comprehensive timely reference for selecting an appropriate brittleness index for their applications,and will also pave the way for the development of a standard definition and measurement method of rock brittleness in the long term.

Identification and Practical Application of Juniper Trees for Hygiene in Tibetan Culture

[Objectives]To understand the function and ritual uses of juniper wood in Tibetan communities.[Methods]Detailed surveys were carried out amongst students of the School of Nationalities at Qinghai Normal University,in order to analyze the practical application and examine the variety of viewpoints concerning functions and importance of juniper wood in Tibetan culture.[Results]193 out of 200 survey respondents completed and returned valid survey questionnaires.Among the responses,slightly more than 95%(185/193=95.8%)of the total number of informants stated that the primary function of juniper wood was its use as an incense,burned as part of religious ritual or home purification.73%(142/193=73.58%)of informants said that juniper wood also represents a kind of sacred wood or prayer-wood(tib.lab-tse).An equal number of respondents also shared about the use of juniper in the making of prayer-beads.About 62%(121/193=62.6%)responded that juniper is used to make prayer-flag poles.About 45%said that juniper wood is understood as a sacred plant and thus"marked"with sheep wool or silk,and therefore protected from other human interaction by such markings.Additionally,49%(96/193=49.7%)of the informants indicated that juniper wood is also used for medicinal incense.Finally,about 34%(67/193=34.7%)noted juniper is also used for medicinal bath.[Conclusions]The survey responses demonstrate that the function and importance of juniper wood permeate several aspects of Tibetan belief and culture.

The Reality and Application of Yin and Yang

Ancient Chinese philosophers discovered Yin and Yang and the laws of Yin and Yang movement during their exploration and practice of nature more than two thousand years ago, and applied them to life, science, philosophy and medicine, playing an important role in the achievement of ancient Chinese civilization. Through historical changes, yin and yang have gradually been regarded as a concept or theory, thus making it difficult for people to understand the connotation of Yin-Yang and make new discoveries and progress. Nowadays, many scholars in China and the West are interested in studying the treasures of ancient Chinese civilization. We illustrate the actual function of Yin and Yang by explaining the essential state of matter, the law of physical movement, the transformation of energy, and then illustrate the practical application in life and science. In conclusion, yin-yang is a key to unlocking the treasures of traditional Chinese civilization, which can help to bring into play its original values, and continue to provide new insights and directions for the development of modern science and the advancement of humanities.
