Abaqus Predicts Real-World Behaviour Of Materials

The Abaqus 6.10 enables designers, engineers and researchers in all industries to perform virtual tests that accurately predict real-world behaviour of materials and product designs. The unified Finite Element Analysis (FEA) and multiphysics product suite for realistic simulation from Simulia is being launched by Dassault Systemes. In response to expanding industry demand for realistic simulation, the release delivers more than 100 customer-requested enhancements for modelling, performance, usability, visualisation, multiphysics and core mechanics.

Abaqus 6.10 also introduces a multiphysics capability for performing Computational Fluid Dynamics (CFD) simulation. This enables users to perform coupled physics simulations with Abaqus/Standard and Abaqus/Explicit, such as fluid-structure interaction between human tissue, a medical device and fluid flow; thermal analysis of electronic systems undergoing convection cooling; or transient thermal analysis of engine-exhaust systems. The release is said to reinforce Simulia's commitment to providing an open multiphysics platform through improvements to its direct co-simulation coupling interface.

This capability allows Simulia partners and customers to couple their applications directly with Abaqus for multiphysics simulation. With this release, Simulia also delivers technology for realistic fracture and failure analysis. Abaqus 6.10 features enhancements to its extended finite element method (XFEM) that improves the process for modelling fracture of composite materials. It also provides performance improvements for parallel processing of simulations that use XFEM, or the implicit dynamic procedure, allowing more simulations to be performed in less time.

The XFEM capabilities in Abaqus 6.10 are said to simplify virtual safety evaluations of nuclear power-plant piping systems and pressure vessels. With this release, realistic simulation of crack propagation based on the cohesive-segments method and linear elastic fracture mechanics is now feasible, while using the implicit dynamic procedure for improved stability. Abaqus 6.10 will be featured at the 2010 Simulia Customer Conference (SCC) on 24-27 May in Providence, Rhode Island.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
