Hi, 

Geometric non-linearity:Incremental solution

1.I've been reading the book by Crisfield on Non Linear finite element analysis and have just started with the first chapter wherein the author introduces geometric non-linearity.

I have some questions on the incremental (Euler) approach here:

I want to know whether my inetrpretations below are correct:

1)The incremental approach makes use of the tangent stiffness which relates small changes in load to small changes in displacement.

2)The "LOAD" is incremented in steps.

Tensor analysis is a very useful tool for continuum mechanics as well as other courses. I wonder which book is best for me. 

I have background of anvanced mathematics, linear algebra.  The book should be comprehensible.

I would like to make a career in Finite Element MEthod with concentration on topics like XFEM,Mesh-free methods--

However, I am yet to mmake a start.To give you my background I ahve a good knowledge of subject of Strength of Materials,Linear Finite Element Analyis-including coding structrial analysis involving beam elements,plate elements,plane stress and plane strain elements-all linear FE.

I have good programming skills-C,VB,MathCAD and know basis of C++ well

I havee just undergone a course on Linear Algebra through the MIT opencourseware.

Hi,

Can anybody throw some light on the wear coupling characteristics between SS347 and 17-4 PH, as well as between Phosphor Bronze and 17-4 PH Steel?

It will be helpful if you could refer to some literature where I can learn about Wear Coupling Characteristics...

Thank You,

Navanee
