4. But the Proliferation of Composite Materials is Challenging Existing
Design Processes
*
Physical prototyping is complex,
time consuming and expensive
Effective integration of composites
into product development requires
an understanding of material
science, design and manufacturing

5. Simulation Based Engineering Has an Important Role to Play in the
Composite Product Development Process – But It Must Be Efficient
When selecting a simulation tool for composite product design, designers should consider
whether a tool has:
Appropriate failure modes (within layers, delamination, debonding and cracking)
Composite layer definition (fabrics, stack ups, sublaminates)
Material reference directions for curved structures (draping, fiber angle, correction and
flat wrap generation)
Critical part identification (failure modes, failed layer and critical load step)
Accurate stress failure evaluation (including 3D)
Ability to examine through thickness behavior using 3D local sub models where thin
shell element approximations are not appropriate
Integration with the overall simulation driven product development ecosystem

6. Not Only is Efficiency Important, The Increasing Performance
Requirements for Composite Materials Mean That Simulations
Must Capture “Multifunctional Effects”
In this example, an integrated comprehensive multiphysics simulation approach enables
the multifunctional performance requirements of an antenna composite radome to be
assessed:

7. Automotive and Aerospace Innovators are Realizing the Benefit of
ANSYS Solutions for Lightweight Composite Material Design
Reduce Weight……
The first monocoque designs of the KTM X-Bow were
engineered without the use of ANSYS Composite
PrepPost. When we did employ the ANSYS software for
composites, we were able to reduce the monocoque’s
weight – a very important aspect of sports car design –
by 20%

More Efficient Workflow……
We are using ANSYS software to develop composites that
reduce the aircraft weight. Using ANSYS Composite
PrepPost within ANSYS Workbench provides accurate
results that allow us to reduce modeling time by up to
65% over traditional solid modeling
