How to Calculate High Cycle Fatigue Strength of Steel without Using S-N curve

Shibashis — Wed, 23 May 2012 14:59:56 +0000

Plotting the S-N curve requires actual fatigue testing of the specimen, and that is why it may not always possible to have an exact S-N diagram for the component of your design interest. Fortunately, there is an work around, an analytical (relatively less accurate) method of calculation for the high cycle fatigue analysis of the …

Five Important Basics of Fatigue Stress Design Calculation

What is cyclic loading? If the applied load (force) on a body changes cyclically (i.e., periodically with time) then the kind of loading is called cyclic loading. For example, when the point load applied at the center of a rotating shaft supported by bearings at both the ends, the acted loads periodically changes between compressive …

Draw Acceleration Vector Diagram in Seven Steps

Shibashis — Tue, 01 May 2012 10:15:26 +0000

In the last article, I have discussed how to draw the velocity vector diagram for a four bar linkage mechanism. The same example I will used here as well for explaining the steps required for drawing the acceleration vector diagram for the same mechanism. Please go through the example problem before proceeding to this …

Draw Velocity Vector Diagram of a Mechanism in Seven Simple Steps

Shibashis — Mon, 09 Apr 2012 18:21:28 +0000

The space diagram, velocity vector diagram and the acceleration vector diagram are the important tools for analyzing a mechanism. With the help of the following example, i will explain the steps required to draw a typical velocity vector diagram. Example: The input data for the above four bar link mechanism is as below: OA=50 mm …

Procedure of Heat Exchanger Design and Sizing Calculation Simplified with Example
