Some practical crack path examples

WAAS MOPS: Practical Examples

The WAAS MOPS describes the method by which a Wide Area Augmentation System (WAAS) transmits its differential GPS corrections and integrity information to users in 250 bit messages. These messages must be decoded and interpreted every second. The corrections even for a single satellite are distributed across several individual messages. The corrections for individual satellites must be combined...

Predictive Data Mining: Practical Examples

The paper addresses some theoretical and practical aspects of data mining, focusing on predictive data mining, where two central types of prediction problems are discussed: classification and regression. Further accent is made on predictive data mining, where the time-stamped data greatly increase the dimensions and complexity of problem solving. The main goal is through processing of data (rec...

Propagation of Crack in Linear Elastic Materials with Considering Crack Path Correction Factor

Modeling of crack propagation by a finite element method under mixed mode conditions is of prime importance in the fracture mechanics. This article describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. Crack - growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress c...

Some Studies of Crack Dynamics

Recent developments in fracture dynamics include the discovery of elastic waves which propagate along moving crack fronts in three-dimensional solids, and the identification of possible sources of the roughening and low terminal speeds of tensile cracks in brittle amorphous solids. Those topics are discussed briefly here.
