Evolution of Failure Mechanisms in Composite Shell Structures Using Different Models

摘要

Modelling of structures on different scales has been a popular subject in the past. Within such a strategy the structural behaviour is modeled on a macro-level, describing the structure itself, whereas the material behaviour is modeled on a micro-level. Here typically RVEs are used. The proper choice of boundary conditions for the RVE is a difficult task in case of shell structures. Here, results have been presented for homogeneous and layered structures for composite materials in (Gruttmann & Wagner, Int J Num Meth Eng 94:1233-1254, 2013) [10]. In the present paper we discuss the influence of material nonlinear behaviour, especially the damage behaviour of fiber reinforced polymers, within the above described setting in comparison to other modeling techniques.
