ABAQUS calls this idea Unified FEA.ĪBAQUS provides the tools required for a wide range of applications within a unified software system. To leverage investments in virtual prototyping, companies are working to consolidate best practices, processes, and tools to create an integrated environment where engineers share methods, models, and results. It is difficult to achieve real PLM integration and maximize benefits when different engineering teams use different tools and models. In many companies engineering groups use more than one finite element analysis program. Virtual prototyping enables creation of better products and shortens time to market.

Companies at all levels in the supply chain recognize finite element analysis as a strategic technology. The numerical model using the SPH/FE method proves its ability to produce the entire physical processes of the impact.ABAQUS products are driven by our vision of Unified FEA in which we deliver best-in-class solutions for a wide variety of simulations with a goal of one model and one analysis tool for diverse analyses. It is demonstrated that the (CEL) method presents smoother curves compared to the SPH method. Results of the coupled SPH-FE simulation were further validated. A Numerical model was developed using ABAQUS/Explicit version 6.14. The distribution of the pressure on the impact surface and the resulting deformation of the structure were discussed. To simulate the entire process, the SPH method was used to model the water jet and the FE method was used for the modeling of the PMMA structure. A water jet with a spherical head was used at an initial speed of 570 m/s to impact on a flat plate made of Polymethyl-Methacrylate (PMMA). Results from the CEL method were experimentally validated in the work of.

Numerical results are compared with the results from other simulations carried out by other numerical method based on the Eulerian Lagrangian (CEL) formulation presented in the work of. In this paper, we present a numerical simulation of a round jet impacting a polymer plate using the coupled Smoothed Particle Hydrodynamics (SPH) and Finite Element (FE) methods.
