Technology Lecture: Modelling and Simulation for Aerospace Industries and Composite Materials

Date: 09 Feb 2009 - 09 Feb 2009

Venue: SIMTech Auditorium, Level 3, Tower Block

Sponsored by Worley Parsons, the objective of this technology lecture is to raise awareness of various possible applications of modelling and simulation in the aerospace industries and composites, and to strengthen local capabilities in the field of composites.

In the analysis of composite materials it has become necessary for engineers to have access to tools to analyse their behaviour, not just during normal design loads but also from those causing permanent damage. It is important to capture the non-linear effects, as there is a high chance that traditional linear analysis will lead to design choices that result in components that are too heavy and negate the advantage of this material choice. Where damage occurs it is important to be able to understand how it will propagate and the effect it has on the part’s durability – how long can the part stay in service, what repair techniques are required?

To solve these problems requires an evolution of traditional modelling techniques and is guiding the development of analysis packages such as the Abaqus finite element software suite. In Abaqus, advanced techniques have been introduced to allow analysts to build the composite lay-up within the virtual model in a process that is analogous to the real world. Capabilities are included to ensure that the simulation captures real world effects as closely as possible and the ultimate strength of materials can be determined using well know criteria, such as Tsai-Wu, and damage estimated using models such as those of Hashin, or user defined models.

In the second part of the presentation, we will look at how virtual models are expected to capture system behaviour. Traditionally, aerospace firms break a problem into different domains of analysis – kinematics, stress, dynamics. In doing this, assumptions and inaccuracies are introduced into the analysis. Abaqus’s Unified FEA capability provides a single computational engine that solves many of these multi-domain problems. Coupling of different loads or physical behaviours, whether structural, thermal or acoustic or from fluids are solved using a single model.

This presentation will provide the perspective of SIMULIA, the Dassault Systèmes brand focussing on simulation solutions. It looks at the progress they are making to develop products that meet the challenges faced by the industry, but will be of interest to all involved in the analysis and engineering of aerospace structures and components and composite materials.

About the Speaker
Kyle Indermuehle was born and educated in the United States and received his B.S. in Aeronautical & Astronautical Engineering from Purdue University in 1999 and his M.S. in structural engineering from University of California, San Diego.  Kyle joined ATA Engineering after university and worked on a variety of aerospace programs including the Pratt & Whitney RL10B-2 rocket engine, analysis and testing of UAVs (Unmanned Aerial Vehicles), and multiple satellite programs. He was also in a team of engineers at ATA that developed a “gravity powered” race-car in their spare time to compete in an extreme downhill event, in which they came in second with Kyle at the wheel. 

In 2006 Kyle joined SIMULIA as the Aerospace Lead and is responsible for driving the strategy and product development efforts for Aerospace customer needs. He is in regular contact with SIMULIA’s aerospace customers including the major aerospace companies and key suppliers and provides a link between industry and the development group within SIMULIA and ensures that the strategic needs of the industry can be met with the software.
