Collaborative development of finite element models for Honeycomb crash test barriers: Crash / Volkswagen

Deformable barriers used in car crash testing are based on aluminium honeycomb blocks covered by aluminium plates. These structures, that largely deform and tear during crash tests, represent a challenge for the…

Enhancements and validation of FPM fluid structure interaction module applied to curtain airbag deployment

Models to represent in position situations based upon uniform pressure assumptions are well established and have been used extensively in the automotive industry for more than 15 years. More recently, in the beginning…

Design of acoustic insulation in ships based on predictive vibro acoustic models

The marine industry has used empirical models to predict transfer functions between source locations and noise sensitive cabins extensively in the past. These empirical methods work well for standard construction types…

Predicting the acoustics of rattle

Buzz, Squeak and Rattle (BSR) are acoustically perceived quality attributes that consistently rank among the top "things gone wrong" in initial quality surveys for many new products. BSR issues discovered late in the…

Windnoise : Coupling wind tunnel test data or cfd simulation to full vehicle vibro acoustic model

Wind noise has become in recent years a significant contributor to perceived sound inside automobiles. Many methods are nowadays available to couple wind tunnel or CFD (Computational Fluid Dynamics) data to a full…

Numerical simulation of powder metal forming process using the SPH Method

The method of Smoothed Particle Hydrodynamics (SPH) is used for the numerical simulation of compaction of iron powder. The character of SPH allows for accurately tracking relevant material properties within a Lagrangian…

Violent Flow using a fully coupled SPH-HE approach

Designing structures located either off-shore or on-shore, able to withstand loads coming from large impacting waves or for entering water poses a major technological challenge. Virtual prototyping using advanced…

Effective and efficient virtual engineering based on reliable virtual prototyping solutions for the oil and gas industry

The present economical climate rewards efficiency and quality in all sectors of industry. To achieve these goals, businesses, including those in oil and gas, rely increasingly on technology for conventional and…

Pressure-corrected SPH with innovative particle regularization algorithms and non-uniform, initial particle distributions

This paper will present an enhanced SPH version, including some particle distribution algorithms, for which many of the well-known drawbacks of the standard SPH method are solved or, at least, relieved. Recent…

Wave impact simulation using smoothed particle hydrodynamics

This paper presents a Virtual prototyping (VP) tool which is built around an explicit Finite Element (FE) software package with an embedded and fully coupled Smoothed Particle Hydrodynamics (SPH) solver that enables…
