The paper titled,
'Predicting residual strength using fully automatic crack growth'
was recently published in the International Journal: Engineering
Analysis with Boundary Elements', Vol.26 No.6.
In recent years,
the need to predict how a product will perform over its life cycle
has increased. Aerospace and other industries need to demonstrate
the durability of designs and plan effective maintenance schedules.
The growth of cracks due to fatigue loads plays an important role
in limiting the life in products.
In this paper,
a new method is presented for the automatic growth of edge cracks
in three-dimensional fracture analysis using BEM. The procedure
described overcomes the current problems with crack growth analysis
that require the user to perform many tasks manually. Applications
are presented which demonstrate the effectiveness of the technique.
The new methods
have been implemented in the BEASY Fatigue and Crack Growth Software
to provide users with highly automated tools for predicting how
cracks grow in structures and components.
Robert A. Adey,
co-author of the paper and Managing Director of CM BEASY, explained
the importance of this paper, "Engineers today not only have
to ensure the performance of their designs but also their durability
over the product's working life. Crack growth is a major threat
to durability and it is essential that the impact can be predicted
and clearly understood. These new developments provide engineers
with the simulation tools to predict if cracks will grow, how fast
they will grow and their expected life.
