Static analysis of space truss structures including inelastic material
and large deformation geometric nonlinearities is considered. Member
material behavior modes include: buckling, yielding, inelastic postbuc
kling, unloading, and reloading. Large deformation behavior is based o
n the nonlinear updated Lagrangian space truss displacement equations.
Due to the interaction of the nonlinear member behavior modes; force
redistributions in a space truss structure can lead to progressive str
uctural failure. The developed model traces the sequence of member buc
kling, yielding, and inelastic member response. Results are presented
to demonstrate model capabilities for representing the inelastic, prog
ressive failure response of space truss structures.
