Fracture Mechanics is used extensively to predict how cracks will impact the durability and integrity of structures and components. In the case of failures, fracture mechanics and modelling can also play an important role in reproducing the failure mode and the assessment of remedial strategies.
BEASY
Crack modelling technologies provides quick and accurate
tools to:
Crack
Wizard
Forget the difficult task of creating a mesh
to represent a crack in a complex 3D model. With the BEASY
crack wizard the whole process is automatic. Select the crack
you need from a library of crack shapes. Simply identify its
location on the model and the wizard does the rest.
High Accuracy
Previously engineers had to use approximate stress intensity data. The BEASY
approach uses the real geometry, loading and materials providing a highly
accurate basis for life prediction. The results also include the effects
of load redistribution, multiple cracks, true crack path and crack shape
modelling. In this application, an analysis of a lap joint is shown where
the behaviour of cracks initiating near the fastener holes are investigated.
BEASY provides the critical information
needed
-
Will the crack
grow?
-
Will it grow in
an unstable fast or
stable slow manner?
-
At what rate will
it grow?
-
To what size can
the crack grow before becoming unstable?
-
What is the residual
strength?
Automatic
Crack Growth
BEASY not only provides stress intensity data but can also predict how the
crack will grow. Remeshing is automatically performed by BEASY where necessary.
The procedure is
highly automated with the crack wizard guiding the user.
Simply define the crack growth model, select the material properties and the loading history and BEASY does the rest.
