Novel methodologies and innovative approaches have evolved over the past years to develop a theoretical framework capable of accurate predictions of cleavage fracture behavior in different cracked bodies by unifying toughness measures across different crack configurations and loading modes. A consensus has emerged in favor of micro mechanics models based upon a probabilistic interpretatio…
Single-parameter and two-parameter fracture mechanics methodologies have some well-recognized limitations which motivate development of probabilistic approaches to brittle fracture. Such approaches can be extended in straightforward manner to analyze the mechanical integrity of structural components subjected to more complex loading conditions. In particular, probabilistic procedures inco…

The increasing demand for energy and natural resources has spurred a flurry of exploration and production activities of oil and natural gas in more hostile environments, including very deep water offshore hydrocarbon reservoirs. One of the key challenges facing the oil and gas industry is the assurance of more reliable and fail-safe operations of the infrastructure for production and tran…
This proposal includes a numerical and methodological research on the effects of stress triaxiality and J vs. CTOD relationships in SE(T) specimens with applications to the assessment of defects in pipelines and risers containing circumferential defects. The focus of this work is in agreement with the research conducted by the Center of Advanced Fracture Mechanics and Structural Integrity…
The offshore industry is moving to deeper waters to explore new oil and gas natural resources. It has motivated the development of efficient and innovative ocean systems; they have to meet severe design requirements, and some restrictions during installation and operation. Rigid risers are a key element to ensure a safe production. These risers are subjected to high levels of plastic def…
