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.
