摘要
Telescoping composite mechanics are described and implemented in terms of recursive laminate theory. The initial elemental scale is defined where simple equations are derived. Subsequently these mechanics are applied to homogeneous composites, hybrid composites, smart composites and composite enhanced reinforced concrete structures. Results from those applications are presented in terms of tables/figures to illustrate the versatility and generality of telescoping composite mechanics. Comparisons with methods such as approximate, single cell, and 2D and 3D finite element demonstrate the predictive accuracy and computational effectiveness of composite telescoping mechanics.
