If the people of Pisa had access to Alex Tomanovich’s footing analysis calculation do you think they would have built that famous ‘leaning’ tower? When you download calculations from the ExcelCalcs repository of solved problems you access a live document encompassing years of knowledge and best practise. Our documents are prepared by working engineers not focused on the academic pursuit of theory but on practical solutions to solve common engineering problems. Best still you’ll always find a ‘Forum Link’ so you can ask the calculation author any question if there is something in it you cannot understand. The ExcelCalcs repository saves you time, taps into expert knowledge and helps you avoid making mistakes.
We recognise that preparing a repository calculation takes a good deal of knowledge of the subject matter and a good deal of effort in laying out the calculation in a readily useable form. So if you have a spreadsheet to share with us we’ll be delighted to share all ours with you. If you don’t have a calculation to share then just $90 per year gives you full access to our repository calculations and a commercial license for XLC our essential engineering addin for Excel. Take a look at the Repository News section below which features new calculations uploaded since our last newsletter, you’ll find something for civil engineers, structural engineers and mechanical engineers.
This year we intend to increase the user base by a factor of 10 so we appreciate all efforts to spread the word about ExcelCalcs. Thank you for forwarding emails to colleagues, adding links to us on your websites and blogs.

A stress concentration is the phenomenon for which stress in a body becomes much more than the nominal stress due to abrupt change in cross section or presence of discontinuities. 'Stress concentration' (often called stress raisers or stress risers) is a location in an object where stress is concentrated. Fatigue cracks always start at stress raisers, so removing such defects increases the fatigue strength. This calculation was used in our consultancy work when we were asked to consider the fatigue implications of adding a keyslot feature in the ends of an actuator arm on a tilting train. Our consultancy work also undertook a finite element analysis of the stress raiser and the calculation was used to validate the results.
