del(w)/del(x), del(w)/del(y) - how can this be found?
I do not understand that math expression. Are you stating a product of derivatives of 'w' w.r.t. 'x' and w.r.t. 'y'?
In my paper on static problems titled "Non-linear analysis of moderately thick sector plates"
- "An iterative incremental approach based on Newton–Raphson method is used for the solution. "
In my paper titled "Nonlinear transient analysis of moderately thick laminated composite sector plates"
- " Quadratic extrapolation is used for linearization along with fixed-point iteration for obtaining the results."
Regards.
you can build a Matlab function.
In my non-linear analysis code made in MATLAB 2013 by Newton Raphson method, the value is not converging at some point. But in other cases it worked fine. Is it because of load increments,i have...
