The saturation of the tearing mode in a plasma column is investigated in the framework of the resistive magnetohydrodynamics approximation. In particular, a perturbative procedure is adopted to evaluate the structure of the magnetic island in three relevant physical conditions, depending on the model for the evolution of the resistivity, which may be affected by the growth of the mode. In cylin...

The effect of an equilibrium sheared ow on the nonlinear evolution of a neoclassical tearing mode is investigated by estimating the inuence it has on the inner and outer layer dynamics of the mode. Two complementary approaches are adopted. A generalized Rutherford model calculation is carried out to estimate the ow contributions to the polarization current term in the inner layer. For the ou...

Although the prognoses of the adhesive bridges are practically satisfactory, some disconnections have been reported. Physical bite, twisting and tearing forces are considered to be the causes for these disconnections. Paired natural human teeth; 2 incisal and 2 molar teeth, were embedded in cold cured resin for fatigue test and axial reduction was slightly performed. Cast bridges which were des...

Supraspinatus tendon tearing is one of the most common causes of the shoulder pain and dysfunction, which often requires a surgical repair. In this situation, proximal tendon stump is usually retracted medially from its original insertion. For successful reduction of the retracted tendon stump to its original insertion, the elasticity of the tendon-muscle unit should be preserved by the time of...

A 65-year-old man developed subacute horizontal diplopia due to left abducens nerve (AN) palsy and excessive eye tearing. Brain MRI revealed a hyperintense T2 lesion with an elongated course within the carotid canal, presenting homogenous contrast enhancement (figure 1). The imaging findings were characteristic for internal artery sympathetic plexus (ICSP) schwannoma compressing AN. Subsequent ...

The mechanical behavior of aluminum hexagonal honeycombs subjected to out-of-plane dynamic indentation and compression loads has been investigated numerically using ANSYS/LS-DYNA in this paper. The finite element (FE) models have been verified by previous experimental results in terms of deformation pattern, stress-strain curve, and energy dissipation. The verified FE models have then been used...

Tearing and interconnecting domain decomposition methods [ 2, 3] are well established for an efficient and parallel solution of various elliptic partial differential equations by using finite and boundary element methods. But in the case of the Helmholtz equation, additional difficulties may appear. Although the global boundary value problem admits a unique solution, local subdomain solvers as ...

Hot tearing formation in both a classical tensile test and during direct chill (DC) casting of aluminum alloys has been modeled using a semicoupled, two-phase approach. Following a thermal calculation, the deformation of the mushy solid is computed using a compressive rheological model that neglects the pressure of the intergranular liquid. The nonzero expansion/ compression of the solid and th...
