Composite Structural Analysis
Materials like steel and aluminum act as general purpose work horses. Excellent for normal use, but sometimes we need more. What if you could do better? Imagine a perfect material, engineered to perfection for performing exactly one task. That is the promise of composite materials. They offer us the ability to engineer the material in addition to the structure. We can shift and swap out material capabilities as needed at different points in the structure. This flexibility also magnifies the complexity of the engineering task.
Most composite parts require several layers of reinforced fiber, all held together by resin. This fiber may be E-glass, S-glass, carbon fiber, aramid, or an unusual combination of all the above. It begins to look like a puzzle, selecting the right combination of materials on the right structure, for the right load conditions.
The mathematics of composite materials become very intensive. DMS utilizes computer automation to rapidly calculate the resulting structure strength for any set of fiber layups. These laminate properties can be applied in FEA analysis or first principles structural analysis. Regardless of the application, DMS contains the labor-intensive complexity inside the computer, letting our engineers focus on better performance for your structure.
