Anybody know how this is done? I want to do a stress analysis on a wing design, but COSMOSXpress yells at me when I choose to use a composite material.
TVP45 said:When you say composite, what exactly do you mean? There are composites like chopped fiberglass that can be reasonably approximated with isotropic bulk properties. Then there are composites like garolite that have distinctly different properties in different directions - Xpress will not work with those. What sort of composite do you have?
TVP45 said:So, I assume you're going to build a real wing? To test or to actually fly? Do you have a shop? Are there safety procedures in place for using nasty chemicals? Do you have some money available? Does anyone have composite experience?
You don't need to answer those now, but should know them when you come back.
Those are definitely benefits. However, since you are doing a study, make sure that you look into the costs associated with production, which are very large. Things to consider are the costs associated with the purchase and operating a large autoclave. Environmental and operational changes for the use of chemicals not normally associated with standard production methods. These costs are definitely not trivial, especially for a company that wishes to change or add the composite capability to their current ones.Jonny_trigonometry said:I'm on a design team doing a trade study on an existing wing design to see if we can make it better. Obviously, composites is a good thing to investigate, since they are stronger, you can lower the weight of the wing and the amount of structure to support it.
FEM (Finite Element Method) for composites in SolidWorks is a simulation technique used to analyze the behavior of composite materials under different loading conditions. It involves breaking down a complex structure into smaller, simpler elements and using mathematical equations to solve for the behavior of each element. This allows for a more accurate analysis of the stresses and strains within the composite material.
FEM for composites in SolidWorks differs from other simulation methods in that it takes into account the anisotropic behavior of composite materials. This means that it considers the different properties of each individual layer within the composite, such as fiber orientation and material properties, rather than treating the material as a homogenous entity.
FEM in SolidWorks can be used to analyze a variety of composite materials, including but not limited to carbon fiber, fiberglass, and Kevlar. It is suitable for both unidirectional and woven composites, as well as laminated structures.
FEM for composites in SolidWorks allows for a more detailed and accurate analysis of composite materials, which can lead to improved design and performance. It also helps to reduce prototyping costs and time, as well as identify potential failure points in the material before production.
While FEM for composites in SolidWorks is a powerful tool, it may not be suitable for all types of engineering applications. It is best used for analyzing composites under static or dynamic loading conditions, and may not be as effective for applications involving extreme temperatures or highly nonlinear material behavior.
