 VIDEO: Structural Analysis & Fatigue

What is fatigue?

 Structural loads are typically one, or a combination, of the following:     • External forces.     • Surface loads (e.g. pressure)     • Body forces (gravity, acceleration, temperature). Structural analysis is the most common application of the FE method. It determines stress, strain and deformation of a component or assembly subject to a range of load conditions. Its a useful tool for ensuring that expensive failures are avoided at the design stage or understanding reasons for failure in service.  The substantial non-linear capabilities of ANSYS® also enable more complex simulations to be undertaken, including: Large deflection Stress stiffening Large strain These features combined with extensive material property functions and state-of-the-art surface contact modelling, mean that complex assemblies can be cost-effectively analysed.

Please take a look at Turan Babacan's amazing calculation entitled "Machine Foundation Analysis and Design" I am sure it is just the thing you are looking for.

I have big reciprocating machine need concrete foundation (250 tons the W of the machine with more that 1000 rpm), the soil is hard in one city and soft in another city (going to fix in different cities). I need excel calculation sheet)
