BEASY Fracture & Crack Growth V10R16

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 simulation 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.

BEASY will be exhibiting at the 2014 Aircraft Airworthiness & Sustainability Conference in Baltimore this April, presenting the latest developments in our Software and Services for Crack Growth Simulation and Corrosion Management in Aircraft Structures.

 

We welcome you to come and visit us at booth 404 to find out more about the capabilities of BEASY products, or how BEASY can help with your particular application. Alternatively to make an appointment to meet Tom Curtin at the conference, or to obtain further information, please contact us

AirworthinessMain12014BEASY Fatigue & Crack Growth

The BEASY Fatigue and Crack Growth software can be used to perform 3D crack growth simulations to support structural life extension decisions. Sophisticated analysis algorithms have been developed to investigate crack growth behavior in complex loading environments. For example load cases can include residual stresses, fretting fatigue, contact loading and thermal stresses. 

Interfaces are also available to enable BEASY to integrate with MSC PATRAN, NASTRAN, ABAQUS, and ANSYS.

BEASY Corrosion Manager Software enables engineers to quickly assess the risk to components and structures of corrosion and the effectiveness of surface protection systems.

 

BEASY Corrosion Manager simulations enable engineers to replace the "find it and fix it" approach and replace it with a more fundamental approach based on an understanding of the corrosion process and the ability to predict its behavior.

 

 

 

Fracture Simulation

Initial ABAQUS modelA focus of interest was BEASY's Fatigue and Crack Growth software used to perform 3D crack growth simulations to support structural life extension decisions and in particular its integration with Finite Element systems such as ABAQUS, ANSYS, NASTRAN and MSC PATRAN. This was demonstrated in a failure investigation where an ABAQUS stress analysis model was available and BEASY was used to perform the crack growth study to gain an understanding of the failure mode.

Predicting Impact of Residual Stresses on Crack Growth

In Damage Tolerant Design the assumption that cracks already exist can lead to overly heavy designs without the consideration of surface and near surface stress distributions. Practical experience and accumulated data have shown surface, near surface and sub-surface stresses are very important to the growth of fatigue cracks and need to be considered when predicting how cracks grow.
