A complete and comprehensive theory of failure is developed for homogeneous and isotropic materials. The full range of materials types are covered from very ductile metals to extremely brittle glasses and minerals. Two failure properties suffice to predict the general failure conditions under all states...
Failure theory is the science of predicting the conditions under which solid materials lose their strength under the action of external loads. The failure of a material is usually classified into brittle failure (fracture) or ductile failure (yield). Depending on the conditions (such as temperature...
on the change in the void geometry and subsequent failure mechanisms are reviewed; (2) a review of some recent experiments on void collapse in single and polycrystalline ductile materials, which seem to corroborate the theoretical predictions and demonstrate how a very ductile material can undergo br...
STATISTICAL THEORY OF FATIGUE FAILURE SIMILARITY 来自 Wiley 喜欢 0 阅读量: 30 作者: V Kogaev 摘要: A similarity criterion for fatigue failure is proposed for stress concentrations. This criterion is based on the relative stress gradient at the point of maximum stress and the length of the ...
Great effort has been devoted to the formulation of strength theories, failure criteria and yield criteria. Many versions of these were presented during the past 100 years. The single-shear criterion Maximum shear criterion (Tresca, 1864), the Huber-von Mises criterion (1904; 1913) and the ...

However, in some special situations such as in case of ductile fracture, the damage evolution and failure depend on parameters characterizing the local stress state instead of peridynamic damage modeling technique developed for brittle fracture. For brittle fracture modeling the bond is simply broken ...
One would either have to solve a series of elastic problems of a body with a growing crack (if a crack opens), or a problem of an elastic–plastic body (if a ductile yield region forms). And why does failure at exactly 2 locations indicate global failure; why not, say, 4 locations?
Consider again in more detail typical uniaxial tensile behavior of a ductile material as shown in Fig. 6.45A. We will describe the behavior in general approximate terms realizing that particular materials may deviate somewhat from our simplified descriptions. As loading begins, the material initially ...
