"A Constitutive Model for Continuous Fiber Reinforced Polymer Plies";
PAMM, 9 (2009), S. 23 - 26.

In the present paper a constitutive model is reviewed which can be used to predict the non-linear behavior of continuous
fiber reinforced laminates with polymeric matrix materials. The constitutive model considers stiffness degradation and plastic
strain accumulation at the length scale of the individual plies (laminae). These effects are modeled via two different phe-
nomenological approaches, however, their interaction is considered when the constitutive equations are solved by an implicit
integration scheme. To demonstrate the predictive capabilities of the individual model parts, examples are given where the
above mentioned effects are decoupled. This way, their impact on the laminate's response can be studied independently.
