Hi all,
i'm looking for informations about an effect called "anticlastic curvature".
I know that bending a strip of a material which have young module and
poisson ratio function of direction, it arise a secondary curvature, in
direction perpendicular to the one of main bending. This effect is called
"anticlastic bending". Is this correct? Where can i find other informations?
How can i calculate equation of deformed surface ?

I need to make FEM simulations of this effect into a bent silicon strip of dimensions 70x1x2mm. Can someone suggest me a software which can simulate anticlastic curvature? It seams this software should take in account for that young module and poisson ratio are function of direction, is this correct ? Here are young and poisson for silicon: young: http://www.ioffe.rssi.ru/SVA/NSM/Semicond/SiGe/figs/wortman651_SiGe.gif

Thanks in advance for any informations, Andrea
