Transcript of Biomimetics

CAE use in Modelling Biomimetic
Engineering Systems

What is Biomimetics?
“the science and art of emulating Nature's best biological ideas to solve human problems”

How and why is Biomimetics
used in engineering systems?
Nature has developed over
millions of years
How can CAE be used to model Biomimetic Engineering systems?
2 groups types of Bio-mimetic modelling
Pros and cons of using CAE to model Biomimetic Engineering Systems

In Conclusion...


Direct Bio-mimetic Modelling

When the forms and principles of nature are
directly reproduced
Indirect Bio-mimetic Modelling
Emulating Shape and Form
Using a Method of Performing a Task
Extrapolating Numerical Modelling
inspired mathematical models
or method
Medical and Dental Application
Evolved for millions of years to create an efficient use of materials and energy
Topology optimisation increases
Nature is Vast and Diverse
Trialled and Tested Solutions
High Performance Structural Composites
Very Difficult to Reproduce on Traditional CAD Packages
Computational Software has Become a Bottleneck

Structural Optimisation

Nature is a useful source of
and can provide the
to our present and future
engineering problems

can be used in a wide range of
biomimetic modeling.

CAD software currently available is limiting our
and our ability to make the best use of nature's solutions.

Biomimicry will only continue to be utilised further in CAE and continue to
natural creative potential

Biomimetics is much more than just imitating nature for aesthetic purposes.
Bio means
Mimesis means

Could we make use of this?
Thank you for listening
Copying Nature could be Used for Immoral Purposes
