DESIGN TOOLS:Dassault Systèmes recently announced the availability of Abaqus 6.9 Extended Functionality (6.9-EF), its technology-leading unified finite element analysis (FEA) product suite from SIMULIA.Designers, engineers and researchers in a broad range of industries use Abaqus to predict the real-world behavior of products, materials, and manufacturing processes. This latest release delivers key new features and enhancements for modeling, advanced mechanics, and performance. These ongoing improvements are enabling customers to consolidate their simulation software, thereby lowering cost and increasing efficiency in their product development process.
New features and enhancements in Abaqus 6.9-EF release include:
• Interactive support is provided for meshing models using cylindrical elements, which can be useful in the analysis of pipelines by oil and gas companies.
• Geometry repair tools in Abaqus/CAE offer greater flexibility and broader scope for systematically adjusting the geometry of a model in preparation for meshing.
• An interface for model change definitions allows the deactivation and reactivation of model regions and contact pairs during an analysis.
• Users can now define direct cyclic and low-cycle fatigue analysis procedures in Abaqus/CAE. Low-cycle fatigue analysis can be used to efficiently predict fatigue life in electronic components such as solder joints.
• Discrete orientations provide a convenient method for accurately defining spatially varying material orientations on models with curved geometries such as aircraft panels and car bodies.
Advanced Mechanics • Viscoelastic behavior can be now modeled with orthotropic/anisotropic elasticity in Abaqus/Explicit, which provides more realistic composite damage prediction.
• A new and efficient method is available for analyzing structures subject to air blast loading, which is useful for safety evaluation in the civil engineering and defense industries.
• Continued advancements in fracture and failure include contour integral evaluation for cracks defined with XFEM and the inclusion of the Virtual Crack Closure Technique (VCCT) in Abaqus/Explicit, which allows users to model brittle fracture of partially bonded surfaces.
• Breakthrough improvement in the implicit dynamics procedure helps solve unstable problems involving contact, buckling, and material failure. Examples include impact inside gear mechanisms and medical device deployment within patients.
• A new iterative solver in Abaqus/Standard provides performance gains up to 20x or more in comparison to the direct sparse solver. The iterative solver is intended for very large simulation problems typically found in applications such as powertrain, oil reservoir, and material microstructure simulations.
• Performance of creating high-quality surface meshes using the mapped meshing technique has been significantly improved. Depending on the part, performance gains of 2x to 40x are possible. This is extremely useful in meshing engine blocks and ship hulls.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
