Simulation of the column bending test using an anisotropic viscoelastic shell model

Finite element simulation of the column bending test (CBT) is carried out using shell elements with anisotropic viscoelastic section properties. The CBT an experimental method for evaluating behavior thin-ply high strain composites (TP-HSC), to support development deployable composite booms space structures. A linear formulation derived and implemented two solution techniques: quasi-elastic (QE) direct integration (DI). model inputs, namely Prony series ABD matrix, are obtained Mechanics Structure Genome. in Abaqus as a UGENS user-subroutine. Recent experiments briefly reviewed, developed including geometrically nonlinear features test. Comparisons analysis results show that capable predicting most measured trends. Nonuniform deformation captured emphasized data reduction considerations. Although relaxation can be QE implementation model, capture residual curvature DI necessary. Residual tests, but not predicted by present suggests viscoplasticity should considered. demonstrative study also shows potential material calibration virtual this work.
