SSD - Pettermann Seminar
Prof. Dr. Heinz Pettermann - Modeling and Simulation of Composite Materials and Components
Institute of Lightweight Design and Structural Biomechanics,Vienna University of Technology, Vienna
Computational predictions of the mechanical behavior of composite materials and components made thereof are presented. For the simulation of components up to peak load and beyond, appropriate nonlinear constitutive material laws and efficient modeling strategies are required, which will be illustrated by two examples.
On the one hand, a constitutive law for unidirectional fiber reinforced polymers is shown. The nonlinearities are attributed to damage as well as plasticity which are treated by a direction dependent formulation. On the other hand, impact simulations on fabric laminates are presented based on a numerical efficient modeling strategy which allows for simulations of large composite structures and components.
