pile

I know nothing about pile foundations, but this sounds readily doable in MapleSim. What do you model? Vertical movement? Lateral movement? If the latter, then do you also have to model bending of the pile?

Hi Joe, thanks for your reply. Yes you can

Hi Joe, thanks for your reply. Yes you can model both vertical and lateral movement, but for now I will concentrate on lateral movement. As you mention above we also have to model the bending of the pile.

The bending of the pile (similar to a beam) is given by the differential equation .

I've been trying to learn how to solve this on Maple without much success...

This differential equation can be solved by

DE := EI*diff(y(x),x$4)+P*diff(y(x),x$2)-p+W=0;
BC := y(0)=0, D(y)(0)=0, y(L)=0, D(y)(L)=0; # boundary conditions
dsolve({DV,BC},y(x)): Y := unapply( subs(%,y(x)), x );
