Fracture Simulation newsletter
While NASGRO is a widely used software tool for fracture simulation it is limited to the simple geometrics included in its library. The interface to NASGRO available in BEASY enables you to build upon the NASGRO capabilities to predict crack growth in more realistic and complex structures whilst continuing to use the NASGRO crack growth laws and materials data.
BEASY’s Fracture & Fatigue Crack Growth (FCG) software enables engineers to quickly develop high fidelity fracture mechanics models based on the actual structural component geometry and loading, therefore providing more accurate critically important data on stress intensity factors, crack growth and crack shape evolution.
- Easily move from NASGRO reference book solutions to more realistic geometry and loading
- Uses a mixed mode stress intensity factor solution (KI, KII, KIII) to simulate accurate, nonplanar, crack shape evolution (not restricted to Mode 1 solutions)
- Predict SIFs and fatigue crack growth under complex multiaxial loading
- Support for multiple cracks and coplanar crack coalescence
- Simulate crack growth in residual stress fields
Predicting the Impact of Hydrogen on Cracks
With the recent interest in the use of Hydrogen as an alternative fuel and the issues regarding its distribution, in this issue we are reviewing the results of a research project in which BEASY engineers investigated the impact of hydrogen on the integrity of gas transmission pipelines.
Software was developed to predict how adding hydrogen to the natural gas distribution network would affect the probability of failure. Hydrogen has been demonstrated to change the behaviour of crack like defects which may affect the safety of pipeline or make it more expensive to operate.
A stochastic approach was developed to assess the failure probability of the gas pipeline due to the existence of crack-lie defects including the operational aspects of the pipeline such as inspection and repair procedures. With various parameters such as crack sizes, material properties, internal pressure modelled as uncertainties, a reliability analysis based on failure assessment diagram was performed through direct Monte Carlo simulation.
The failure probabilities of each defect and the whole pipeline system were obtained from the simulation and different inspection and repair criteria were investigated to determine an optimal maintenance strategy.

In April (20th-23rd), BEASY was due to be exhibiting at the Aircraft & Sustainability Conference, presenting our fracture mechanics & corrosion risk assessment simulation software and services for aerospace structures.
Unfortunately the conference has been postponed but please find below a preview of the BEASY presentation.
In April (20th - 23rd), BEASY will be exhibiting at the Aircraft Airworthiness & Sustainability Conference where we will be presenting our fracture mechanics & corrosion risk assessment simulation software and services for aerospace structures.
BEASY will also be attending the NACE Conference (15th - 19th March), at which we will be presenting the following paper, addressing research work into the corrosion risk for structures and improvement to material degradation prediction using a fracture mechanics framework :
Discover how the output from a galvanic simulation model is used to determine the spatial distribution of corrosion damage; providing a guide for the location of discrete corrosion damage features that are analysed using stress fields from structural models and crack growth simulations
See How Engineers are Reducing The Risk Of Corrosion In Aircraft Structures Using Computer Simulation
BEASY will be again attending the Aircraft Airworthiness & Sustainability Conference where we will be presenting our fracture mechanics & corrosion risk assessment simulation software and services for aerospace structures. The conference will be held in Washington DC from April 22-26, 2019. In addition to presenting BEASYs comprehensive capabilities for crack growth assessment and simulation BEASY will be presenting new tools and technologies.

NEW PRODUCTS & SERVICES TO BE PRESENTED AT AA&S 2019
BEASY Model Cutting Tool
The BEASY model cutting tool is an "add on" feature to further simplify the creation of BEASY fracture and crack growth simulation models from FEM models such as NASTRAN, ABAQUS, ANSYS, PATRAN etc
BEASY Fracture Assessment Tool
BEASY Fracture Assessment Tool (BEASY FASST) can be used to quickly assess the impact of a crack on the structural integrity of a structure. The tool can be used with FEM or BEASY models to predict how stress the intensity factor (SIF) varies with crack size for a crack located at any position on the model. This can be used as a fast assessment tool before a full scale simulation is performed.
BEASY POLCURVEX software is used by design engineers to quickly assess the corrosion risk of material combinations exposed to aqueous environments.

BEASY Polarisation & Corrosion Rate Prediction
BEASY POLCURVEX software is used by design engineers to quickly assess the corrosion risk of material combinations exposed to aqueous environments. Galvanic corrosion is one of the primary, and most costly, corrosion mechanisms observed when different metals and finishes are coupled. BEASY POLCURVEX provides a more accurate, laboratory validated, method to predict corrosion rates based on the identification of crossing points for material polarization curves.
Galvanic corrosion is commonly assessed by comparing differences in metal potential (e.g. galvanic series in seawater table) with higher corrosion risk being associated with larger differences in metal potential. However recent research results obtained during development of the revised military standard, MIL-STD-889C suggests that potential differences do not fully account for the corrosion kinetics and can lead to wrong material compatibility decisions.
Given the high cost of corrosion maintenance many companies are searching for corrosion modeling tools to support the paradigm shift from “Find & Fix” to “Predict & Prevent/Manage”. The BEASY POLCURVEX software provides critical information to designers, focused on metal compatibility and coating performance of new designs and retrofits and maintenance engineers concerned with scheduling inspections to look for corrosion.
