ESAComp for Enhancing HyperWorks in Composites Design

4 - Element loads and properties are

avai lable in ESAComp for further

investigation of details. Through-the-

thickness plots illustrating stress, strain

levels, or reserve factors, for the layers in a

single element provide valuable insight on

what are the critical mechanisms and how to

possibly improve the lay-up. Further,

dedicated modules for bonded and

mechanical joints are available.

2 - ESAComp makes use of HyperMesh comments, in

supported profiles, to ensure seamless transfer of object

names. Laminates can be modified and applied to your

structure, or updated within an optimization loop using

ESAComp's batch capabilities, which also makes it very

powerful for repeated tasks.

1 - ESAComp not only enables efficient laminate

build-up and evaluation using materials from its vast

databank. These lay-ups, including material data, can

also easily be exported easily to HyperWorks in

various solver profiles, e.g. OptiStruct, NASTRAN,

Abaqus and ANSYS.

3 - After solving, element data can be transferred to

ESAComp for composites post-processing using the

advanced failure criteria implemented in ESAComp,

such as Puck 3D and LaRC03. Results for reserve factors,

critical layer and type of failure at element level can be

visualized in HyperView, as well as results at ply level.

ESAComp licensing

�Analysis and design software for layered composite

structures

�For material selection, conceptual and preliminary

design, analyses of details, …

�Stand-alone tool that interfaces with general finite

element packages

�Originally developed under contract for the European

Space Agency (ESA) to meet the needs of the aerospace

industry

�Today used worldwide in all industries utilizing high-

performance composites

�Explore possibilities. The combinations of composite

material systems and structural concepts are limitless.

The ESAComp Data Bank gives a good basis for trying

potential materials for a design. The analysis capabilities

of ESAComp allow performing trade-off studies, for

instance, between the use of solid laminates, sandwich

panels or stiffened panels.

�Be efficient. Use the right tool for the different phases of

the project. The FE environment is not ideal for laminate

level studies or lay-up design. In the early phases of a

project, the structural elements of ESAComp allow fast

analysis without a full geometric model.

�Avoid pitfalls. Designing with composites is a challenge.

For instance, a potential failure mode can be missed

easily without a careful assessment of the structure.

ESAComp complements the capabilities of FE tools in

doing this. Advanced ESAComp capabilities like the

probabilistic analysis may become handy in verifying the

real performance of the design.

�Optimize your design. Besides the user environment that �allows practical hands-on optimization of designs,

ESAComp integrates as part of more complex

optimization systems.��Learn about composites. ESAComp helps structural

engineers with limited composites experience to get

familiar with the topic. For composite experts, the in-

depth capabilities of ESAComp mean there is also

something new to learn.

�ESAComp FE export interface allows transfer of

materials and lay-ups to HyperWorks (use of ESAComp

Data Bank, environment dependent material data,

practical user interface for lay-up definition, laminate

design capabilities, …)

�Material and laminate data is exported in solver

dependent format for various HyperWorks supported

profiles (OptiStruct, NASTRAN, Abaqus, ANSYS, LS-

DYNA).

�ESAComp post-processing interface in HyperWorks

allows transfer of FE results and related material and lay-

up data to ESAComp for failure analysis and for further

visualization of results in HyperView (application of

advanced failure criteria, visualizations of failure modes

and critical layers, through-the-thickness plots in

ESAComp, design improvement using ESAComp tools,

…)

�ESAComp post-processing is available in HyperWorks

12 and further enhanced in HW 13. Currently supported

solver profiles include OptiStruct and NASTRAN.

ESAComp is available on-demand through Altair Partner

Alliance - paid-up and lease licenses through

Componeering and its distributor network.

Interfaces for HyperWorks are included in the base

version of ESAComp under all licensing approaches.
