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?
Do you know what is Fatigue Failure? Fatigue failure refers to the failure of the machine component due to repeated or cyclic loading. Due to the fluctuation in the stress, this failure occurs. Let’s discuss the Fatigue failure briefly. Fatigue Failure Fatigue Failure is defined as the brittle fractures that occurred while a repeated 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 […]
What are the Principal Stresses and Principal Planes?
From all the way, we have discussed the different types of stress and strains, Now its time to understand what are the principal stresses.

First of all, we have to understand […]
What are the different Non-Metallic Materials?
In material science, materials are classified into four groups Metals, Non-metals, Ceramics, Composites. In this article, we are going to discuss Non-Metallic Materials. The Non-Metallic materials are used in engineering due to their less density and flexibility, resistance to electricity, heat and most importantly it is available at low costs. Non-Metallic Materials Before going into the topic it […]
What are the different Non-Ferrous Metals?
The metal which is consisting of the main constituent other than the iron is known as Non-ferrous metals. For example aluminium, copper, lead, nickel, tin, titanium and zinc.
