Efficient Engineering of Layered Composite Structures
Composite materials are formed from the combination of two or more
layered materials, each having very different properties. Composite
materials have become a standard for manufacturing products that
are both light and strong. Additionally, composites provide much flexibility,
enabling products with complex shapes, such as boat hulls or
surfboards, to be manufactured.
Among the many challenges
of designing products from
composites is defining the
specifications of each layer
that constitutes the composite
material. To engineer layered
composites, a designer must
find the best combination of
lamina, including the number
of layers involved as well as the
thickness and relative orientation
of each layer. As with homogeneous
materials, stresses,
deformations and other performance
indicators will help determine a product’s performance under
actual working conditions. A range of failure criteria, from simple to
more advanced formulations, is usually used to study how the layer
material and their orientations affect the design of the product.
ANSYS® Composite Prep-
Post software provides all the
necessary functionality for the
analysis of layered composite
structures. An intuitive interface
efficiently defines materials,
plies and stacking sequences;
it also offers a wide choice of
state-of-the-art failure criteria.
ANSYS solvers provide the foundation
for accurate results, while
additional computations for the
failure criteria are performed
within the ANSYS Composite
PrepPost application.
