Aero Forming - An Introduction of Collaborative Engineering

The decrease of physical prototypes and the growing power of simulation in the design process require greater control in the design chain calculation. This is the main reason for the arrival of SDM in the perimeter of…

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…

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…

Numerical simulation of a helicopter ditching with emergency flotation devices

Smoothed Particle Hydrodynamics (SPH) is used to model the ditching of a helicopter. Helicopters have a high centre of gravity, are not integrally watertight so tend to roll over and sink within seconds of landing on…

Study on mechanical characteristics of lithium-polymer pouch cell battery for electric vehicle

In order to characterize deformation and failure behaviors of Lithium-Polymer pouch cell battery and its components, various mechanical tests were performed. Uniaxial tensile properties of electrodes, separator, and…

Modeling Tsunami-Structure interaction and subsequent flooding to assess the safety of NPP and industrial structures

The 2011 events in Japan when the Fukushima Daiichi NPP suffered a major accident have focus the attention on the risks associated with major tsunamis. After recalling these events and the associated safety requirements…
