Title

Nonlinear Transient Finite Element Of Stressed Sandwich Composite Arches

Abstract

Dynamic stability of prestressed sandwich composite arches subjected to impulsive loads is investigated. The complexity of the problem rises from sequential fabrication of the arch. A nonlinear finite element model is developed that traces the stress path in the composite stressed-arch as it undergoes the fabrication process. Upon erection of the arch, its stability under dynamic loads is studied and compared with that of the conventional rigid arch. A convected corotational formulation is developed to represent the large displacements and large rotations of the finite elements, and Wilson-θ method is used for dynamic analysis.
