The Effect of Surface Irregularities on The Elastohydrodynamic Lubrication of Sliding Line Contacts
… equation in finite difference form by the Newton-Raphson technique for systems of nonlinear equations. The results of the case studies show that the presence of surface irregularities has a significant effect on the fluid film pressure distribution, film thickness, and state of stress in …

Geometric and Material Nonlinear Analysis of Three-Dimensional Soil-Structure Interaction
… laws. The analysis adopts the original Newton-Raphson technique coupled with incremental approach. Different elasto-plastic laws based on Von-Mises, Drucker-Prager, critical state, and cap criteria are incorporated in the formulation and computer code, and they can be used depending on …

Nonlinear finite element analysis of sheet pile interlocks
… incremental equilibrium equation is solved by a Newton-Raphson technique. Convergence criteria based on incremental displacement, incremental internal energy of the system, and the changes in contact forces can be chosen to advance or terminate the iteration process.

Stabilized Finite Element Formulations for Flow Problems
… of this formulation with a fixed-point iteration technique. We show for a number of example problems that the Newton-Raphson technique converges quadratically. For transient problems, we show that consistent Newton-Raphson approach does not converge in the vicinity of bifurcations such as the …

Hydrodynamic stability of liquid films adjacent to incompressible gas streams including effects of interface mass transfer
… eigenvalues are obtained numerically using a Newton-Raphson technique. One of these modes has nearly the same speed of propagation as a Kelvin-Helmholtz wave for small wave numbers and hence it was called the modified Kelvin-Helmholtz mode. The variation with respect to the disturbance wave …
