NONLINEAR BENDING OF STRAIGHT BEAMS

Submitted by kannanstkn on Mon, 03/25/2013 - 06:40

Can any one please help me out in Nonlinear analysis of beams using Direct iteration method or Newton Raphson.

Here i am producing some of algorithms from the book of J.N.Reddy,"An_Introduction_to_Nonlinear_Finite_Element_Analysis__2004".

I have a doubt in the term DW, whether that is the difference between transverse dispalcements of Consecutive Nodes or the difference between transverse dispalcements of Node on Consecutive iterations.
