Title Peridynamic Applications for Orthotropic Materials.
Publication Date Sep 2012
Media Count 50p
Personal Author D. Liu T. Jia
Abstract It has been shown that peridynamic simulation of damage process does not require any knowledge of the damage location and orientation prior to the simulation. This is fundamentally different from finite element analysis which requires knowledge of damage location and orientation in advance to impose special finite element mesh, such as initial damage elements and cohesive zone layers, for damage simulations. This prerequisite becomes even more challenging when inhomogeneous and anisotropic composite materials are of interest. In addition, peridynamic simulation does not require remeshing at the end of each damage processing step since it is a mesh free method. On the contrary, finite element analysis does. Based on these difference, peridynamics should be more suitable for simulating dynamic damage process in composite materials which have different properties in different locations and different orientations.
