Bars¶

bar2e(ex, ey, elem_prop) → Ke¶

Computes the element stiffness matrix Ke for a 2D bar element.

bar2s(ex, ey, elem_prop, el_disp) → N¶

Computes the sectional force (normal force) N for a 2D bar element.

bar2g(ex, ey, elem_prop, N) → Ke¶

Computes the element stiffness matrix Ke for a geometrically nonlinear 2D bar element.
