Like a child selecting parts to construct a Lego model engineers bring together blocks of science to create new designs. These building blocks could be a load calculation, a beam calculation, a weld calculation, a fatigue calculation or any other calculation from a myriad of engineering topics. As...

I have been chasing up feedback from new users signing up to XLC Pro accounts in the last month. I am delighted with their positive feedback.
“I started using XLC but I am now insisting that my whole team use the add-in .“
“It is a great tool for validation and pres...
Engineering training - “I run a team of engineers and whilst there are plenty of soft

You are probably familiar with our tools of mass knowledge distribution on our website but ExcelCalcs also works more closely with corporate partners providing engineering training and engineering consultancy services. What’s more these services and ExcelCalcs subscriptions are availa...
ExcelCalcs eFormulas aims to replace traditional engineering formula books providing innovative functionality to copy from our webpages and paste directly into Excel.
Once in Excel it is easily edited to suit your own problems this functionality is far more flexible than 'stuck on the web'&n...
At some time or other you will have been given someone else’s spreadsheet only to be left scratching your head not having a clue as to what the calculation is doing. If you are wise you will not use it because you can’t understand it. If you are wiser still you’ll use our...
In our good calculation guide we emphasise the importance of sketches in calculations but you can produce interactive 3D wireframe sketches by incorporating Turan Babacan’s latest upload. Turan uses 3D charts to great effect in his Excel FEM programs. Andy Pope also has a 3D chart spr...
A new version of XLC is in the final stages of development which will be compatible with the 64 bit version of Excel 2010 (currently it works with the 32 bit version of Excel 2010, 2007 2003 and 2000). We’ll keep you posted with progress. Please send us details of any features you ...
Fatigue of Welded Structures
Two day in-house fatigue seminars for engineering professionals.
COURSE LEADER: John Doyle BSc(Eng)., C.Eng., MIMechE., ACGI was born in
1965 and is a graduate of London’s Imperial College with almost 30
years of experience in solving engineering problems. After rising to the
position of Chief Mechanical Engineer with Bombardier Transportation he
started his own engineering consultancy in 1995 called MoreVision. It
specialises in engineering analysis of railway vehicles and mechanical
equipment. His website delivers solutions to engineering problems and
welcomes over 20,000 unique visitors per month.
WHY ENROL ON THIS COURSE? Fatigue occurs when small cracks grow under the action of repetitive loads progressively weakening a part until it suddenly fractures without warning. Welding is one of the most common joining methods for structural materials but they introduce additional complexities to the fatigue process. Thus weld fatigue is the most significant factor affecting the structural design of machines such as construction equipment, railway vehicles, mining and other mechanical equipment. Engineering theory is set in the context of real life case studies to reveal strategies to overcome fatigue problems and develop your eye for fatigue prone details.
Fatigue has been the root cause of many engineering disasters so register your interest in the course and make sure it does not happen on your projects.
