Applications of Advanced Composite Simulation and Design Optimization

Usage of fiber reinforced composite material entered an new era when leading aircraft OEMs took an unprecedented step to design and manufacture essentially full composite airframe for commercial airliners. Composite structures offer unmatched design potential as the laminate material properties can be tailored almost continuously throughout the structure. However, this increased design freedom also brings new challenges for the design process and software. Moreover, as a relatively new material, composite behaviors are more complex and less fully understood by design engineers. Therefore, reliable simulation for highly complex events like bird strike and ditching can play an important role in shortening the product design cycle. This paper showcases two area of CAE tools for composite applications. On advanced simulation, bird strike simulation with Altair RADIOSS [1] is demonstrated on an aircraft underbelly fairing. On design optimization, an airplane wing structure is designed using an innovative composite optimization process implemented in Altair OptiStruct [1-3]. OptiStruct has seen increasing adoption among aerospace OEMs, as demonstrated in the Bombardier application process described in this paper.

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.

Materials and Material Management

When simulation results don’t make sense, what checks do you perform? Besides the modeling aspects of loads and boundary conditions, mesh sizes, right formulations, etc., the most often overlooked cause of problems is the wrong assignment of materials and properties in a solver input deck. In the midst of running many simulations it is so easy to modify values that users forget that what they intended for a part is not what is being analyzed. Identifying the correct material values and assigning them is such a crucial step in your analysis that any mistake can compromise the results and design decisions you make based on simulation.

Biomedical Research at the Scripps Clinic: Modeling Orthopedic Implants with Altair HyperWorks

Every year, countless people — regardless of their age or level of physical activity — begin to experience the effects of osteoarthritis, a degenerative joint disease. As we age, the cartilage that cushions the joints begins to deteriorate. The head of the adjacent bones begin to break down from the friction, causing pain in the joint. When the condition worsens and non- surgical remedies are exhausted, surgeons may recommend joint replacement. Typically, titanium alloy implants are lined with plastics that act as cartilage and are fixed in place with cement or screws by the surgeon. The implants can give patients a new lease on life, dramatically reducing pain and improving mobility. However, questions naturally arise in the patient’s mind: How much range of motion will I have in the new joint? How much strength will I recover? And how long will the new joint last?

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments

The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

HyperWorks Improves Development Processes in Automotive Industry

In 2008 PWO Germany (Progress-Werk Oberkirch AG) had to develop and produce a new steel made automotive cross car beam (CCB) for the dash board of a new car. PWO received the CAD model, the design space definition and other pre-defined standards of the component from the customer and developed and produced the fitting cross beam based on this information. PWO used the HyperWorks Suite to develop the component. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. HyperForm was used to check the production feasibility of the individual components and for metal forming simulation tasks. It was important for PWO to have a software suite available that could cover all simulation tasks within one graphical user interface and licensing system.

Step Change in Design: Exploring Sixty Stent Design Variations Over Night

Traditionally, computer analysis has been used to verify the structural performance of a proposed stent design. The stent deployment process consists of multiple stages (e.g. crimping, springback, expansion etc.) which is highly non-linear inducing material plasticity and load transfer via component contact. A single structural verification assessment would require a couple of days to compute on a PC. This paper investigates how recent developments in Computer Aided Engineering (CAE) and computer hardware combine to facilitate the rapid exploration of many stent design variations. It is demonstrated that by utilising these technologies, over sixty stent design variables can be assessed overnight provides valuable design sensitivity information and an optimum stent geometry configuration.

Upfront concept design optimization on a all terrain vehicle frame resulted in a 9% mass reduction. Using Design of Experiment (DOE) methods, peak accelerations during crash decreased by 22%.

Failure Criteria for Stamping Analysis in RADIOSS

In this paper, several failure criteria are compared in their ability to predict necking point and failure propagation during a forming process. The paper has been presented at the 2014 IDDRG Conference in Paris, France.

Smart Multiphysics: Explosives and Concrete Material Simulation in RADIOSS



Partner Spotlight: Key to Metals

Interview with Key to Metals CEO Viktor Pocajt

Electromagnetic Interference in Automotive and Aerospace

Both the automotive and aerospace industries face ever-increasing Electromagnetic Interference challenges. In the automotive case, new problems arise due to proliferation of electric and hybrid cars, which carry high-voltage systems, and of wireless infotainment and safety systems, which use high frequencies. The aerospace industry’s challenges are exacerbated by the use of composite materials and by the need to protect against lightning strikes. This presentation will discuss many of the challenges and explain how they can be met with simulation. A few practical examples involving cable harnesses will be analyzed in more depth.
