Dr Sharon Mellings from BEASY recently attended the ICAF conference in Helsinki and presented a paper describing some recent work on the simulation of corrosion and fracture damage.
BEASY staff attended the 2015 AA&S Conference in Baltimore in April and met with many customers to discuss their applications and update them about projects underway at BEASY.
We had a lot of new interest at our booth this year in the areas of fatigue crack growth in residual stress fields, fracture behaviour of composite plates as well as the modelling of corrosion related damage. There was also considerable interest in the BEASY Corrosion Manager software which is used to predict and simulate galvanic corrosion in structures such as aircraft.
An interesting article was published in a recent issue of the NACE Materials Performance magazine.
Researchers used modelling tools to design effective cathodic protection systems that address challenging seawater conditions and coating damage from ice abrasion.
According to researchers Min-Jeong Lee, senior engineer, and Chae-Seon Lim, principal research engineer, both in the Material & Coating Research Department at Samsung Heavy Industries, Co., Ltd, South Korea, the performance of a CP system for a ship's external hull is dependent on several factors, including the geometry of the ship's hull, the resistivity of the surrounding seawater, the chemicals in the seawater, and the degree of coating damage. The ICCP design for many commercial vessels is often based on current density (CD) calculations and the designers' experience rather than an analytical method. For an icebreaker travelling in Arctic conditions, the researchers note, this traditional approach to CP design may not result in an adequate amount of corrosion protection for the hull in this environment.

BEASY attended the NACE Corrosion Conference in Dallas this March where we were active at the exhibition as well as presenting and participating in the technical sessions and exchange groups.
It was great to meet many friends at the conference and discuss how modelling can be used to improve and optimize CP systems as well as providing further confidence in their performance as part of "due diligence" activities.
In addition to the activities by BEASY staff there were papers presented at NACE incorporating BEASY modelling. Please click here for more information
BEASY will once again be attending the annual NACE Corrosion Conference, which this year is being held in Dallas, Texas, between 16th and 19th March.
We will be active in both the conference program and exhibit hall showing our corrosion modelling services and software.
Please come and visit us at booth 21096, or if you would like to set up a meeting to discuss any aspect of BEASY's modelling and software services, please contact us
BEASY will also be attending the Aircraft Airworthiness & Sustainability Conference where we will be presenting our corrosion and fracture mechanics simulation solutions for aerospace structures. The conference, will take place between March 30th and April 2nd in Baltimore, Maryland.
We welcome you to come and visit us on booth 206 to find out more about the capabilities of BEASY simulation products, or how BEASY fracture modelling can provide the solutions you need. Alternatively to make an appointment to meet Tom Curtin at the conference, or to obtain further information, please contact us
An article in December 2014's MP magazine looked at the effect of grounding on the cathodic protection (CP) potential distribution at an oil station, which had been studied using BEASY's corrosion and cathodic protection simulation software.

An interesting article was published in the September 2014 issue of the NACE Materials Performance magazine. The article presents design considerations and some of the challenges a corrosion engineer encounters while designing a cathodic protection (CP) system for offshore wind turbine foundations. The authors were Sameer Ayyar, Jacob Jansson and Ruth Sorenson from COWI A/S Copenhagen, Denmark.
BEASY Fracture & Crack Growth 10.0r16 provides a great number of new and advanced features that will enable engineers to improve fracture analysis and crack growth simulation to provide deeper design insight. The new release not only incorporates improvements and enhancements to the core BEASY Fracture & Crack Growth software but also to the model creation and visualisation tools as well as the Finite Element System Interfaces.
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.

BEASY participated in a very busy NACE Corrosion Conference in San Antonio last month. We were active in the conference program and exhibition hall, highlighting corrosion modeling services and software. It was good to see many friends and interested engineers visiting us at our booth. There were a number of papers presented during the Technical Program which featured some engineering projects carried out by the BEASY engineering services team and by customers. Details of the papers presented can be found here
Guy Bishop presented a paper entitled "Recent Signature Modelling Studies To Predict The Impact Of Hull Openings And ICCP System Anode Failure" at the recent MARELEC 2013 conference in Hamburg, Germany, July 16th-19th 2013.
The study used computer modelling to assess the robustness and sensitivity of the vessel ICCP system to the impact of anode failures, damage, coating degradation, hull opening and appendages etc. Of particular interest was the corrosion related electric and magnetic signatures. The study used some recent developments contained in the latest release of the BEASY Corrosion Defence modelling software. The results demonstrate how a computational modelling approach is one of the most effective tools for the design of corrosion control systems and optimization of ship electric and magnetic signatures.

Sharon Mellings recently presented a paper on some recent developments to improve the modelling of cracks in aircraft structures. Generally aircraft structures are highly complex structures involving complex load paths, however cracks are often localised features involving just a few of the structural components. One particular location for damage is near to riveted connections where localised forces can lead to fatigue damage problems. These areas can be where stiffening ribs are attached to the aircraft skin, where two or more skin sections are overlapped or where holes in the skin are covered by additional doubler panels.
The paper presented a model which can be used to predict the crack growth path and residual strength of the structure. The simulation technology was tested by applying it to a large scale structure consisting of a number of panels stiffened by ribs and stringers. Virtual Testing of the structure was performed to predict the structural failure due to crack growth and the estimated fatigue life of the structure.
