3D-printed lattice-like composites can be designed to detect their own strain, load and damage, according to the University of Glasgow. Crucially, the team has a complete theoretical model of the substances’ piezo resistivity – its resistance change as it deforms. “Imparting piezoresistive behaviour to 3D-printed cellular materials gives them the ability to monitor their own performance without any additional hardware,” ...

Danish company Vind-Vind is developing a turbulence model for the effect of wind on structures in complex environments. It will eventually include the atmosphere high above the volume of interest with wind gusts from different directions. As such, said Vind-Vind CEO Per Jørgensen, wind-tunnel measurements are not good enough and he needed real-world measurements throughout a large volume of atmosphere ...

Connector maker Harwin has teamed up with TraceParts to offer 3D models of its connectors as well as models of its board-level EMC shielding and PCB hardware. “Models are available in all current file formats for engineers to integrate directly into their CAD system,” according to Portsmouth UK based Harwin. The same deal has put Harwin’s parts onto TrustedParts, a ...

Following on from acquiring Numeca and Pointwise, Cadence Design Systems has introduced suite of computational fluid dynamics (CFD) software for vertical markets including automotive, turbomachinery, marine and aerospace. Called Fidelity, it “introduces a next-generation flow solver featuring high-order numerics, scale-resolving simulations and massive hardware acceleration”, according to Cadence. Included are specialised flow solvers for marine and turbomachinery applications, as well ...

Nexperia has released electro-thermal models for some of its mosfets, many of them automotive qualified. It “developed these models in close partnership with a Tier 1 OEM whose requirements could not be satisfied by any others currently available”, according to the company. “Simulation models for mosfets usually include a limited number of device parameters modelled at typical operating temperatures. Nexperia’s ...

Fuel cell control systems will need to be highly sophisticated if the technology is going to find its way into transport, according to German hydrogen and fuel cell research centre ZBT, which is developing it for trucks and busses. In hydrogen fuel cells, hydrogen is fed to the anode while air is fed to the cathode. An anode catalyst, typically ...

Risc-V intellectual property creator SiFive has qualified models for its core portfolio from Oxford-based Imperas Software – as well as signing a distribution deal with Valtrix. Imperas’ models for SiFive processor IP are an instruction accurate programmer’s representation with full functionality including user, privileged, system and debug modes, plus configuration options for Risc-V vector extensions and custom instructions. “The models deliver ...

Cadence is aiming at high-end PCBs and motherboards with a 3D electromagnetic modelling package called Clarity 3D Solver. It is intended particularly at the fastest parallel and serial links, such as DDR4 and 112Gbit/s – the latter achieved using PAM4 four-voltage-level signalling. “Chips are getting much faster,” Cadence product director Brad Griffin told Electronics Weekly. “There are no shortcuts with 112G ...

Would you believe it, model boats can do 130mph – powered by steam. Take a look at this video: https://www.youtube.com/watch?v=CJBG7k3DIms

Consumer demand for intelligent devices and components based on embedded software shows no signs of slowing down, believes Robert Dickau, Principal Engineer at Flexera Software. The challenge for manufacturers is to produce families of these devices in a variety of market-specific configurations, without increasing production costs. In these situations, the use of embedded licensing to distinguish product configurations provides a ...
