We present hybrid fast sweeping methods for computing first-arrival traveltime of the qP, qSV and qSH waves in two-dimensional tilted transversely isotropic media, based on solving the anisotropic eikonal equation. A factorization approach is applied to resolve the source singularity near the point ...
A novel fracture pressure prediction model was proposed for transversely isotropic formations. • The influence of anisotropic tensile strength on fracture pressure is non-negligible. • As the anisotropic degree of tensile strength increased, the fracture pressure decreased. Abstract Fracture-initiation...

By minimising the difference between PDO and the new approximation, we compute optimal coefficients based on a least-squares method, and then derive the new time-space domain PAWEs in both 3D transversely isotropic and orthorhombic anisotropic media. Although the new PAWE contains a Poisson's ...
The problem of determining the transversely isotropic tensor closest in Euclidean norm to a given anisotropic elastic modulus tensor is considered. An orthonormal basis in the space of transversely isotropic tensors for any given axis of symmetry was obtained by decomposition of a transversely isotropic...

The anisotropic model provides a further step towards a more realistic condition of the Earth, in contrast to the classic solutions in isotropic media. The transverse isotropy of the layered media can indeed, in some ways, characterize the geological conditions of the Earth [59]. We mention ...
These include the transversely isotropic elastic layered half spaces under static surface and dislocation loads [5], [6], and the exact solution for anisotropic MEE simply supported plates under static loading [7]. Chen et al. [8], [9] and Yu et al. [10] analyzed the dynamics of planar...
