We have discussed how the stress concentration effect the different cross-section mechanical components. Due to the irregular stress distribution, stress concentration increases and let the component failure. So how we can reduce the stress concentration? There are few methods of reducing stress concentration. Methods of reducing stress concentration Before getting into the topic we have to […]
What is Stress Concentration? How to reduce it?
We have been seeing the shafts with the different cross-sections. What would really happen when a mechanical component has a different cross-section? Would it affect the stress distribution in the component? Yes exactly. Let’s see how the irregular stress distribution results in stress concentration. Stress Concentration Stress concentration occurs due to the irregular stress distribution. This irregular stress […]
Difference between Fatigue Limit and Endurance Limit
As we discussed earlier What is fatigue failure. The Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Whereas the fatigue strength or fatigue limit or Endurance limit is used to describe the material property that the cyclic load can be applied to the material without causing the failure. […]
What is Fatigue failure in material science?
In Strength of materials, Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Due to the fluctuation in the stress, this failure occurs. Let’s discuss the Fatigue failure in briefly. Fatigue Failure Fatigue failure is defined as the brittle fractures occurred while a repeated load or cyclic load […]
What are the various Theories of Failure under static load?
Prediction of the failure of the machine component in the case of the uniaxial stresses(Simple tension or compression) is very simple by understanding the Stress-strain curve. Predicting the failure of any machine component is complicated when the machine component is subjected to the different types of Bi-axial stresses(Component subjected to two different stresses) or Tri-axial […]
