The development of a new computer code called PLEXIS-3C is described. The program, based on finite elements, treats transient dynamic problems in structures and accounts for the presence of compressible fluids. It presently contains models for 1D, 2D and 3D dynamic analysis of structures. Compressible fluids can be treated in 2D, while 3D models are currently being completed and validated. Nonlinearities of material (plasticity, viscoplasticity) and of geometry (large displacements and rotations, large strains) are accounted for. Models for fluid-structure interaction phenomena are also available. The program will continue its development with the introduction of new material models and improvement of the present capabilities, especially in the 3D applications domain.
