Efficient Engineering Based Modeling of Layered Composite Structures

This presentation is by Program Manager Rob Jopson. It’s a given that the simulation models we build are intended to capture and predict physical behavior, the data used to create them is not always representative of the manufacturing process used to build the physical part. For layered composite parts in particular, this mismatch can cause significant overhead in managing the simulation data as the model is created and evolves. To solve this problem, Altair’s ply-based modeling methodology strives to maintain a 1:1 relationship between the simulation data and the manufacturing process, independent of solver. The latest developments of this methodology will be presented as a workflow in the new Composite Browser, available in HyperWorks. The recording is about 18 minutes long and was originally presented at the 2020 ATCx Composites.

Composites at Altair

This presentation is by Markku Palanterä, Director Composites Business Development, Altair The composites design and simulation suite by Altair is actively developed with a holistic view to cover all stages of the process from material modeling all the way to the certification of composite structures. On the material modeling side, the focus is on continuous further development of Altair’s multiscale modeling technology for continuous fiber composites and injection molded plastics, but not forgetting further application areas, such as additive manufacturing. The ply-based composite modeling in Altair HyperWorks has recently undergone a major update to achieve an improved, more efficient modeling workflow. This together with planned further developments tie the modeling even better with the manufacturing to create realistic models of composite components as built. Altair’s solver technology for implicit and explicit analyses can utilize multiscale material models to accurately describe composite material nonlinear behavior up to failure. Altair’s unique composites optimization technology is being enhanced with the repeat laminate concept that provides added efficiency and user control over lay-up design. To further complement the idea of an integrated system with all the necessary composites capabilities, the Composite Stress Toolbox has been introduced in HyperWorks to support design and certification.

Curing, Cracking and Distortions in Epoxy Composites. Simulating Manufacturing Processes using Finite Element Approach

This presentation is by Dr. Tomasz Garstka and Graham Barnes, LMAT Ltd. Manufacturing induced deformations and residual stresses are an unavoidable consequence of processing composites at elevated temperatures. A number of mechanisms have been identified causing residual stresses and distortions, including mismatch in the thermal expansion, cure shrinkage of the resin, consolidation and tool-part interaction. These mechanisms usually act collectively through the curing process and may lead to severe changes in the laminate characteristic. When cured and exposed to natural environment moisture swelling, as well as subsequent stress relaxation mechanisms lead to further geometrical changes. A novel cure simulation solver is demonstrated here with the application to typical aircraft components. The recording is about 10 minutes long and was originally presented at the 2020 ATCx Composites.

New Simulation Strategies to Slash Architectural, Engineering & Construction Project Timing and Costs

Leading design firms join Altair to discuss high-fidelity simulation solutions for all experience levels to realize efficiency gains up to 40%. Today, architectural design firms face two primary and often conflicting challenges: increased project complexity and compressed delivery schedules. Due to the large scale nature of AEC projects, frequent change orders, and on-time delivery pressure, more often than not the ability to use traditional simulation methods for design guidance and validation is simply time and resource prohibitive. This situation is further exacerbated when trying to achieve an aggressive design aesthetic, working with new materials, and balancing form and function with sustainability initiatives and construction safety standards. Recent user experience advancements and the introduction of novel simulation technologies now enable a broader community of designers and civil engineers to confidently and rapidly apply simulation earlier and throughout AEC projects. This webinar will explore this transformational shift and its positive business impact on project timing and costs through the lens of leading AEC design firms and thought leaders at Altair.
