Influence of Cell Topology on Mode I Fracture Toughness of Cellular Structures

A cellular structure is made up by an interconnected network of beams or plates which forms the edges and faces of cells. This paper proposes three different micromechanical models to determine the fracture toughness values of cellular materials such as rigid polyurethane foams using the finite elem...
