Fracture Mechanics
is used extensively to predict how cracks will impact
the durability and integrity of structures and components.
BEASY Software
provides predictive tools to improve product durability.
Discover problems during design not during testing:
What
size crack will grow?
Virtual Fracture
Testing
Using the BEASY
crack modelling technology the behaviour of cracks in
complex structures and components can be easily predicted.
Zoom in on the critical areas and
model cracks using the real geometry. The models can
also be automatically generated from FEM models.
Investigate
possible:
- In service
damage
- Manufacturing
defects
- Material
defects
- Uncertainties
in design loads which can lead to crack initiation
or growth.
Ensure design integrity using
prediction models:
- What size crack will grow
- When does a part need replacing
- How can the design be modified
to increase durability.
Details such as holes, fillets, radii,
and bosses are where high stresses occur. These details
are generally eliminated in finite element models because
of the time required for accurate meshing. However these
geometric stress risers are often the sites of premature
part failure.
BEASY provides the tools to quickly and
accurately predict the stress levels and assess the
risk of crack growth. Zoom in on those critical life
limiting design features
Flaw Assessment
Flaw assessment is frequently required
to identify how material inclusions or crack-like flaws
will affect durability. In this pplication the growth
of an embedded flaw is predicted including details of
the growth rate and path. Note how the crack shape adapts
to the stress field.
Contact, Wear and
Fretting To obtain
information on wear or fretting, an accurate model of
the contact surface is required. In this application,
a fretting test simulation provides accurate data on
the slip and stress history on the surfaces.
