Can I get Stiffness Matrix from SW??

Gopal Koya May 12, 2014 12:27 PM

Hello all,

Is it possible to obtain the exact stiffness matrix for a beam structure with non circular cross section?

For example, I modelled a drill-bit in solidworks and now I want the exact stiffness matrix when the loading and boundary conditions are specified. This is a bit different from general beam element of circular cross section as the cross section of drillbit contains warping effects. Hence, I need this through solidworks. Please help me.

SW can't model a body that twists as a beam element. In general, beam elements require a constant cross-section. More can be read here.

section properties for beams are available in the interface i believe. however as shaun noted, the twist is unlikely being taken into account.
