黏弹性断裂力学(英文版)

This book includes two parts, namely Viscoelasticity and Viscoelastic Fracture Mechanics. It is divided into seven chapters. Chapters 1, 2, 4 and 6, and Section 7.8 to 7.10 deal with the basic theory of viscoelasticity, which includes linear viscoelasticity, non-linear viscoelasticity and thermo-viscoelasficity. Chapters 3, 5 and 7 deal with linear viscoelastic fracture mechanics, viscoelastic fracture mechanics that taking into account the non-linear effects in the failure zone at the crack-tip and non-linear thermoviscoelastic fracture mechanics. Many of the contents are the summation of the basic theory established in a long period when I was researching the crack instability problem of Zhexi diamond-head buttressed concrete dam in Hunan Province of China. ..

The emergence and development of Viscoelastic Fracture Mechanics are closely related with the wide application of new viscoelastic materials and the employment of a variety of materials in extreme conditions, such as high temperature, high stress level, etc. People find that a serious event of fracture usually occurs not immediately after the load application, but suddenly occurs under the application of the load after undergoing a period of time. We call this type of fracture as delayed fracture. A crack of buttressed concrete dam may occur..

Fracture mechanics provides an important tool for the study of the influence of sharp flows, such as cracks in a structure on its mechanical performance under external loading. The sharp flows result in complicated stress and displacement fields even when the structure is made of a linear elastic material. . The situation is further complicated by non-linear and time-dependent response of the material. Although linear elastic fracture mechanics is now well endowed with several quality textbooks, viscoelastic fracture mechanics is not so for..
