Form and Function: Metal 3D Printing of Hybrid Lattice
Altair, Materialise and Renishaw have collaboratively created a prototype of lattice structured spider bracket; a lightweight, functional structure which echoes biological forms found in nature. The synthesis of computational design technology with performance based lattice optimization, automatic surface smoothing and re-design with metal additive layer manufacturing, resulted in the creation of this unconventional, structurally efficient, manufacturable bracket that unleashes designing potential and creativity, freeing creators of common manufacturing constraints across the entire project from conception, product performance to its realization. The printed part shows how true bio-mimicking of 3D patterns reduces stress concentrations and produces a custom tailored design that embeds organic beauty and freedom of design.

OptiStruct now extends topology and sizing optimization to assist in the efficient blending of solid-lattice structures with smooth transitional material volume. This new technology satisfies an unmet need, since no tools previously existed for lattice structure design with optimal and structurally efficient material distribution.

An Interview with Ben Farmer of Robot Bike Co. Discussing the Development of their R160 Bike with Altair
Robot Bike Company (RBC) is a new startup established in the UK by aerospace engineers and mountain biking enthusiasts who identified the potential of combining additive manufacturing technologies with carbon fiber to, in their own words, “create the best bike frames possible”. To deliver a customizable, lightweight, high strength bike, RBC’s frame was intended to be created from carbon fiber, a material very common in the industry. The carbon fiber tubes, as well as the bike’s other components and systems were to be joined by additively manufactured titanium ‘nodes’, manufactured based on the specification of individual riders. Altair ProductDesign’s engineering team was tasked with optimizing these joints, which included the head tube, seat post and chain stay lugs, to ensure they were as lightweight as possible and still able to withstand the forces of downhill mountain bike riding, all while being fit for the AM process.

A shell facet model for preliminary design of cylindrical composite structures
The laminated composite lay-up design typically involves trade-offs between material selection, thickness of the layer, orientation of the layers, and the stacking sequence. Finding the right structural concept early in the design process leaves resources for the detailed design. Many structural members made of laminated composite materials have the form of thin walled cylindrical shells that are prone to buckling. Thus it is desirable to find structural designs that satisfy global requirements for structural stability early in the design phases. In this work, thin-walled cylindrical composite shells under different loading conditions have been studied for structural stability. The simulation is performed with a shell facet model implemented in the ESAComp software. Preliminary design tools for structural stability of thin-walled cylindrical composite shells are demonstrated and discussed.

The goal of the engineers was to take full advantage of the design freedom AM offers and to create an aluminum component that would be significantly stiffer while at the same time lighter than the original design. In addition, RUAG’s engineers also wanted to cut down design and development time to get results and the final component faster.

Using HyperWorks to Generate Electrically Large Surface Meshes for Radar Cross Section or Antenna Placement Simulation

Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance
The automotive industry, in its constant quest for weight reduction, is increasingly considering composite materials as a substitute for sheet metal components to meet future fuel consumption standards. However, composite forming processes are expensive and difficult to control because of the complexity of the material behavior with fiber and matrix layers or plies and its dependency on many parameters, such as non-linearity of tensile stiffness, effect of shear rate, temperature and friction. Hence, numerical simulation could be a viable approach to predict material behavior during composite forming. The objective of this study is to highlight capabilities of RADIOSS™ to simulate forming simulation of composite plies made from woven fibers, each ply modeled as a layer of woven fibers along two directions of anisotropy, warp and weft. For validation the well-known double dome model published in NUMISHEET’05 proceedings is used. The compared result is the shear angle after stamping that is, the final angle between warp and weft fibers, at several prescribed points on the ply. The variation of this angle has a strong impact on material characteristics which severely deteriorates when a critical value is reached. Hence, a study on crash simulations is performed, after mapping fibers angles from stamping simulation.

Weld Distortion Optimisation using HyperStudy
Distortion induced in parts due to the cooling of welds complicates automated manufacturing lines in the automotive industry. The resulting deformation leads to additional investment such as end of line machining to correct affected assemblies. Utilising optimisation software a welding pattern can be found which retains the intended performance of a part while reducing the distortion induced from welding. Weld locations may be optimised alongside welding sequence to allow process requirements to be considered within the early design stage. This leads to high performance, low distortion assemblies which can ultimately be manufactured at the lowest possible cost.

Nuovo Pignone, now a key technological component of GE's Oil & Gas business, began life 100 years ago as a foundry. Today more than 20,000 machines – turbomachinery, compressors, pumps, valves, and metering and fuel distribution equipment – manufactured by this GE business are operated worldwide by major companies to keep petroleum products moving from oil rigs to storage facilities to refineries to distribution points.

Sequentially Cold Forming Simulation of Complex Shaped Heavy Plates
This was a 2013 European ATC presentation given by Dipl.-Ing. Steffen Garke from Universität Rostock. Swept lines and derived double curved shapes are not only satisfying an esthetic concept, particularly in ship and offshore structure their implementation is essential for certain aspects like drag of the hull. In ship building it is often about one of a kind or miniseries manufacturing. Therefore the demand for a flexible production process for complex formed plates is at hand.

A design approach for lightweight car body construction with an example on the micro-car “ec2go”
This was a 2013 European ATC presentation given by various presenters from Imperia GmbH Abstract. With increase in demands for special purpose vehicles such as electric vehicles, small series production is gaining more importance in automotive industry. However due to restricted amount of resources available, these manufacturers have to face a number of challenges, high development costs, longer design-optimization loops, high manufacturing costs are some to name. Additionally, no compromise can be made with the passive safety and lightweight characteristics of the vehicle design.

Composite Plate Optimization with Practical Design Constraints
Composite free size optimization has the potential to generate weight savings and performance improvements for many applications of composite structures. Key to realizing such improvements is practical application of design and manufacturing constraints in the optimization model.


A Comprehensive Process for Composite Design Optimisation
Composite structures offer unmatched design potential as laminate material properties can be tailored almost continuously throughout the structure. Moreover, composite laminate can be manufactured to fit the ideal shape of a structure for aerodynamic and other performances. However, this increased design freedom also brings new challenges for the design process and software. It is shown in this paper that optimization technology is well suited to exploit the potentials that composite materials offer.
