NEW BEASY Fracture & Crack Growth Software Release

   

BEASY Fracture & Crack Growth 10.0r16 provides a great number of new and advanced features that enable engineers to improve fracture analysis and crack growth simulations and provide deeper design insight.

 

The new release incorporates improvements and enhancements to the core BEASY Fracture & Crack Growth software, allowing more crack growth simulations to be run automatically (such as analyses where only part of the crack is growing) and reducing the need for user intervention.

 
This new version builds on previous BEASY releases (10.0r12 and 10.0r14) to provide a comprehensive simulation tool to predict crack behaviour.

Partial crack growth - one of the significant new features is that the crack growth algorithms have been enhanced to enable crack growth simulations to be performed automatically for a much wider range of applications.

 

The new capability is of particular value where residual stresses exist within the structure. The residual stresses can prevent the crack opening thus reducing the Stress Intensity Factors thereby resulting in slower crack growth. As the residual stresses can vary locally within the structure (particularly if they have been applied as some form of surface treatment) this can result in parts of the crack front growing at very different rates or in some cases not growing at all along part of the crack front.

 

This development also benefits models where crack growth on part of a crack front slows as it approaches a compressive load region but there is significantly faster growth at other parts of the crack front. This is typically the case when looking at crack growth through a gear tooth for example.

The new capability can also be used when simulating multiple cracks where one crack is growing slowly or not growing at all.

 

In the example shown in Figure 2 a corner crack is growing in a structure where the stress intensity factor at the crack front at the lower edge is significantly less than at the upper edge thus resulting in slower crack growth at that location. This change along the crack front results in a change in the crack growth profile which is used to create the successive crack meshes representing the crack surface as it grows.

Training
Courses are held regularly at BEASY's offices near Southampton in the UK, and at Billerica, Massachusetts in the USA.

Courses are also held at customers' sites and can be tailored to meet the specific needs of the client.
