Application Example

Composite Materials

• Objective: Low Weight

– Develop an exciting and modern sports cars, the KTM X-Bow, using a monocoque made from carbon composites materials so the external skin provides the vehicle’s structural support.

• ANSYS Solution

– Use ANSYS Composite PrepPost to model and analyze the composites monocoque.

– Analyze different possible layups, fiber orientations and composites materials.

– Analyze the failure behavior of the composites design under different load scenarios.

• Value of Simulation

– KTM Technologies reduced the weight of the composites monocoque by 20 percent using ANSYS simulations.

Application Example

Composite Materials

• Objective: Low Weight

– Reduce aircraft weight by employing lighter composite materials for the load introduction rib (LIR) of an aircraft’s wing flap.

• ANSYS Solution

– ANSYS Composite PrepPost modeled the composite layup. This innovative approach allows modeling composites by building up plies in the same way that they are manufactured.

– The post-processing capabilities of ANSYS Composite PrepPost allowed evaluation of failure criteria, including transverse shear stresses and interlaminar normal stresses.

• Value of Simulation

– ANSYS Composite PrepPost provided simple pre- and post-processing of composite designs within ANSYS Workbench, significantly reducing modeling times - allowed time savings of up to 65 percent.

Application Example

Composite Materials

• Objective: High Strength

– Take into account a large number of characteristics, including strength, stiffness, weight, durability, ease of manufacture, type of bike and rider preference.

• ANSYS Solution

– Composite PrepPost software provides innovative modeling and analysis capabilities

– Identify critical areas along with the load case for which failure might occur from state-of-the-art failure criteria and layer-wise analysis

• Value of Simulation

– The stiffness and resistance characteristics of fiber-reinforced bicycle components can be optimally adapted to meet design requirements; design efficiency is significantly improved. Compared to typical trial-and-error development methods used in the bicycle industry, the number of cost- and time-intensive physical prototypes was greatly reduced.
