The same technique is followed for supernode circuit analysis as an alternative for nodal circuit analysis because this method streamlines those complex circuits by closing the voltage element and minimizing the number of reference nodes for every voltage source. In the super mesh analysis, the curren...
An improved variation of the nodal integral method to solve partial differential equations has been developed and implemented. Rather than treating all of the nonlinear terms as the so-called pseudo-source terms (to be approximated), in this modified version of the nodal integral method, by ...
The analysis is performed on the cross-section as shown in Fig. 5.6b. Sign in to download full-size image Figure 5.6. Torsion of rectangular prismatic bar. The use of a warping function is governed by the formulation in which displacements are given as u=-yzθ,v=xzθ,andw=ψ(x,y)...
We present an algorithm for hp-adaptive collocation-based mesh-free numerical analysis of partial differential equations. Our solution procedure follows a
Using the nodal integration and the discretized velocity field, the kinematic shakedown problem is expressed as a nonlinear optimization problem. The optimization problem is solved by separation of plastic and non-plastic/rigid zones using a repetitive algorithm. Eventually, the efficiency of the ...
In these methods, the motion of interior grid and material points is related by a linear function as (2.90)vg=a+B vm where a and B are the vector and matrix of constant scalars, respectively. Substituting equation (2.90) into (2.87), the rate of internal nodal forces is obtained as ...
In computation of flow problems with moving boundaries and interfaces, including fluid–structure interaction, moving-mesh methods enable mesh-resolut
