Numerical Modeling of the Impact Behavior of a Polyurethane Foam Specimen

Abstract:

The increasing interest for new materials in designing of new structures led to a real need to use powerful analysis tools, able to take into account correctly, their specific performance. Advantages of multilayer structures are now well understood, these materials having already part of the structural components of aeronautics and not only. The use of polyurethane rigid foam (PU) has grown rapidly, due to the excellent properties of energy conservation, a good combination of mechanical strength and weight - lower than other traditional materials with similar mechanical properties. In this paper the authors create a numerical model of polyurethane foam which will be used in further studies of impact behavior of sandwich structures with a polyurethane foam core, coated with steel or aluminum thin layers.
