An inverse temperature field problem of the theory of thermal stresses
Nuclear Engineering and Design, 1981Abstract Unlike the investigations reported in the literature, which are restricted to the inverse problems of heat conduction, the current study presents an analytical approximate solution to an inverse problem of temperature field in the thermal stresses theory. Based upon the so-called internal responses of a different kind, an approximate form of

Tectonics, 2015 Measurements and Inverse Modeling for Far-Field State of Stress Estimation
SPE Annual Technical Conference and Exhibition, 2001Abstract The near-well stress concentration is affected by several factors, including the far-field stresses, the well deviation relative to the principal stresses, and the well completion configuration (e.g., open-hole or cased, cemented and perforated.) The stress concentration has been known to greatly affect the fracture initiation ...

Inversion of stress field in Guangdong and its adjacent area
Acta Seismologica Sinica, 2008We determine the stress field of Guangdong and its adjacent area by using focal mechanism solutions of 137 earthquakes and obtain tectonic stress tensors in 12 zones. The result shows that the azimuth of maximum principal stress σ1 is approximately WNW in southwestern Fujian, southern Jiangxi, Guangdong’s Heyuan and the Pearl River Delta, NW in ...

On a certain inverse problem of temperature and thermal stress fields
Acta Mechanica, 1980The paper discusses the method of solution of an inverse problem of one-dimensional temperature and stress fields for a sphere, a circular cylinder and an infinite plate. The inverse problem describes the dependance of the boundary conditions of different types on the prescribed temperature state or stress state within the body under consideration, in ...

Studying the stress field variations in the Vrancea-zone using clustering-based stress inversions
2022<p>The SE-Carpathians indicate significant geodynamic activity, especially in the external part due to the current subduction processes. This part is the so-called Vrancea-zone where the distribution of the seismic events is quite dense considering the relatively small area (around 30*70 km).</p><p>The authors ...

Modified Inversion Technique for Determining the In-situ Stress Field
SPE Western Regional & AAPG Pacific Section Meeting 2013 Joint Technical Conference, 2013Abstract One of the major challenges of oil industry is to predict the in-situ stress field accurately. Accordingly, different techniques have been developed to predict the reservoir stress field in the past decades. Inversion Technique is a powerful method which was developed to determine the minimum and maximum horizontal stress ...
