Estimation of the threat of IEMI to complex electronic systems

The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their…

RCS predictions for electrically large complex structures

Radar Cross Section (RCS) prediction of electrically large complex structures is a technical challenge. This paper presents the study carried out to examine the applicability of PAM-CEM Solutions, the simulation package…

Analysis of influence of plastic bumper on radio wave characteristics

From the standpoint of vehicle appearance, vehicle radar units should be located behind plastic bumpers. Plastic bumpers are made of dielectric material, which causes reflection, scattering, refraction, and diffraction…

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…

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…

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…

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…
