Laminate composites are often the answer to ever increasing lightweighting demands. While significant advances were made regarding mechanical strength, there remain a number of challenges regarding their vibro-acoustic properties. Composites are indeed lighter and stiffer, which as a result, tends to decrease their sound insulation properties at critical audible frequencies. One thus needs a thorough design of the structure to avoid acoustic comfort failure. During this webinar, a unique approach to predict the vibro-acoustic response of laminate composites will be presented. Supported by short computational times and high fidelity predictions, this new feature of AlphaCell enables to optimize the design at an early stage of the project. In addition to accurate predictions, this model further enables to reduce the computational cost in FE analyzes by providing material cards with condensed properties.

Cost optimization is a driving force in all fields of industry, with every manufacturer competing to provide a cost-effective solution to the end customer. The paper addresses how to perform an early-stage design of components with emphasis on cost optimization and without consuming too much of a construction designer's precious time. The main objective of this paper is to generate a proposal for a car seat design, based on free size optimization and cost optimization using Altair OptiStruct commercial engineering software.

eStress' needed to develop a practical and generalized approach to assess the behavior of curved composite beams under corner unfolding loading for design sizing. This process shows how HyperWorks, LAP and CoDA worked together to achieve this.

Composite materials have become the structural material of choice in many industries due to their improved strength to weight ratios compared to more traditional materials. A design methodology specific to composites is necessary to take full advantage of the unique performance and manufacturing capabilities of these materials. This webinar demonstrates Altair’s composite optimization methodology which produces an efficient final design while meeting engineering requirements.

In this webinar, we discuss how to:

• Identify efficient ply orientations and shapes for a given part
• Determine the necessary number of each ply to meet engineering requirements
• Produce a final, fully defined laminate for further analysis and manufacturing
