A continuum model for the nonlinear analysis of beam-like lattice structures
Technical Report
·
OSTI ID:6961739
The purpose of this study is to develop an equivalent continuum model for structures which consist of beam-like lattice elements (i.e., lattices with aspect ratios like those of a solid beam). A finite element discretization of the equivalent continuum will be used to get a reduced order model of the structure. Both dynamical and statical behavior will be considered and nonlinearities will be restricted to those arising from geometrical considerations only. The development will be restricted to planar lattices and the normal assumptions of frictionless pin or rigid joints will be made for the discrete lattice.
