Many studies on automotive mass reduction have been undertaken over the years by various steel, aluminum, magnesium, and composites consortia, all expounding the virtues of substituting a particular material. Altair has participated in studies with all these organizations over the years and has understood the strengths, limitations, and constraints of working with various materials.

Composites are flying high in the aircraft industry as manufacturers look for ways to reduce weight, improve performance and create a better customer experience. Composites, of course, weigh considerably less than conventional aluminum and titanium materials, and they offer a number of other benefits as well. These include high stiffness-to-weight ratios, better fatigue performance, non-corrosive characteristics, and less susceptibility to crack growth.
That said, composites are subject to their own distinct problems. The damage modes are far different from those of metals. Delaminations and matrix cracks are common damage modes, and both can occur internal to the structure with no visible damage on the surface. This poses a problem for inspection, so many aircraft manufacturers are embedding sensors into the structure to detect damage. The manufacturing processes also are much different for composites, necessitating different equipment and tooling. The joining methods for composites require different techniques and analysis methods to design and certify.

Much more goes into a golf club than simply wood, iron and graphite. To shape the performance, the distinctive appearance, the personalized feel and even the sound of the club striking the ball, manufacturers must precisely engineer every aspect of the design.
Market–leading golf club manufacturer Cleveland Golf is a pioneer in the design and production of advanced clubs and the developer of the number-one wedge in the golf industry. The company’s engineering research team uses HyperWorks to drive product innovation and tune performance of forward-looking designs while developing market-leading woods, irons, wedges and putters.

Program Manager – Durability
Product design in today’s environment requires careful attention to all aspects of the design, including such issues as sustainability, recyclability and durability of the product. Durability of ground vehicles can be particularly challenging because of the way the vehicle is used and the roads on which the vehicle is driven and the product design can change significantly during both the design phase and the product lifecycle. Testing the product is the most common way to verify durability, but testing is also expensive and time-consuming. Virtual durability testing methods in today’s computing environment offer rapid, repeatable predictions of the loads a vehicle will experience and the resulting life that the product will have when put into service.

Multi-Objective Optimization in the Design Cycle
Design optimization seeks a design that minimizes the objective function while satisfying design constraints. Real-world design problems are usually characterized by the presence of many conflicting objectives. Therefore, it is natural to look at the engineering design problems as multi-objective optimization problems. For example, we may want to maximize range and payload mass while trying to minimize manufacturing costs for an airplane design.
