Linear and Nonlinear Circuits: Basic & Advanced Concepts In this chapter, we define the potential functions for two-terminal and n-terminal resistive elements. Moreover, we introduce some fundamental results concerning the variational principles for nonlinear resistive circuits. M Parodi,M Storace - ...
Hourglass control in linear and nonlinear problems 来自 Semantic Scholar 喜欢 0 阅读量: 376 作者:T Belytschko,SJ Ong,WK Liu,JM Kennedy 摘要: Mesh stabilization techniques for controlling the hourglass modes in under-integrated hexahedral and quadrilateral elements are described. It is shown that the...
Furthermore, nonlinear chromatic integration occurs independently of nonlinear spatial integration, depends on contributions from the rod pathway and on surround inhibition, and may provide information about chromatic boundaries, such as the skyline in natural scenes....
With the new proposed techniques, solving a large class of nonlinear elliptic boundary value problems will not be much more difficult than the solution of one linearized equation. Similar techniques are also used to solve nonsymmetric and/or indefinite linear systems by solving symmetric positive ...
A semi-numerical method for the solution of dynamic problems of linear and nonlinear structures is presented under the unifying aspect of sources of self-stresses. Conceptually applications are possible to the Finite Element and the Boundary Element Method in time as well as in the frequency domain...
