An efficient finite element method to take account of the nonlinearity magnetic materials when analyzing three dimensional eddy current problems is presented in this paper. The problem formulated terms vector and scalar potentials approximated by edge node based basis functions. application Galerkin techniques leads a large, nonlinear system ordinary differential equations time domain. excitati...

One of the significant difficulties in representing behavior reinforced concrete structures mathematical models is post-cracking non-linearity. And so, slabs are no exception to rule. Still, usual analysis for this structural element verified elastic regime when tensile strength considered. This model acceptable service limit states but not ultimate state. These aspects associated with great di...

A boundary element method is applied for the numerical solution of a boundary value problem for a two-dimensional steady-state bioheat transfer model of the human eye. The human eye is modeled as comprising four distinct homogeneous regions. The boundary condition on the outer surface of the cornea is non-linear due to heat radiation. An iterative approach is used to treat the non-linear heat r...
