"Wolff’s Law"
Das Gesetz der Transformation der
Knochen (The Law of Transformation
of Bone), 1892.
"As a consequence of primary shape
variations and continuous loading, or
even due to loading alone, bone
changes its inner architecture
according to mathematical rules and,
as a secondary effect and governed by
the same mathematical rules, also
changes its shape."

Airliner Wing
“….an innovative rib design, which
resulted in an optimized weight saving
over 500kg per aircraft."

Crane Boom
The component’s dead weight was
reduced by approximately 20 % and
load capacity was increased by up to
400 kg. Apart from its higher handling
efficiency, the redesigned stick now
provides improved protection for
equipment attached to it.

Engine bracket
23% weight savings compared to initial
design, casting constraints to ensure
manufacturability

Tension – Topology Optimization
Often used by
experienced FE
analysts late in
product development
Offers the biggest
benefit when used
