What exactly the notch sensitivity means? From our previous article, we have discussed how a fillet or a notch or a hole can reduce the stress concentration. But in this case, it will look somewhat different. actually, due to the presence of the notch or a hole in the body, the body tends to have […]
In Mechanical Engineering, Machine Design is subjected to creating new or Advanced machines. This involves improving the existing machines to better machines.
The design process is a time-consuming process which includes implementing an Idea and considering the commercial and economic aspects, Making the idea into a shape in the form of drawings by keeping the available resources in mind to make the actual Idea into a life.
What are the Methods of Reducing Stress Concentration?
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?
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. The maximum stress induced in a plane is called the principal stress and the plane at which the maximum stress induced referred to the principal plane where the shear stress is […]
What are the different Casting processes?
In the previous article, we have discussed what are the different manufacturing processes. The manufacturing process turns the raw material into finished products. There are different manufacturing process which uses different technologies and machinery to get the final products from the raw material. In this article, we discussed the different casting processes. Casting Processes Casting […]

What are the different commonly used cross-section properties ?
When we say common Cross-section properties, what we will think of? First of all Sectional area, Section modulus, the moment of inertia, and few other. The different cross-section properties for the different cross-sections such as circular, square, rectangular and trapezoidal and triangular are discussed briefly in this article. 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. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. Non-Ferrous Metals Having lightweight, high conductivity, corrosion resistance […]
What are the different Case Hardening processes?
Case Hardening is also known as Surface Hardening. Sometimes also are known as the Face Hardening. The process of hardening the surface of the components is known as the Case Hardening. There are different types of Case hardening processes available. We have discussed each of them here! Case Hardening / Surface Hardening The process of Hardening […]
What are the different Heat Treatment processes?
In material science, the Heat treatment processes used to impart the physical properties by altering the microstructure. We have discussed the purpose of the heat treatment and the different heat treatment processes briefly. Heat Treatment Heat Treatment includes the heating and cooling of the metal to obtain the desired mechanical properties without changing the chemical […]
Stainless Steel – Types, Properties Applications, Grades
We all know Stainless steel is notable for its corrosion resistance property. Stainless steel is an alloy of iron and chromium which will significantly improve the corrosion resistance property. Along with the chromium, there are few other alloy elements to make the stainless steel more strengthen and harden and tough and increase the few other […]
What are the different Carbon Steels and their Properties?
Steel is the alloy of iron and carbon. Steel consists of carbon content up to a maximum of 1.5%(Somewhere it will be mentioned as up to 2%). The other elements of steel are silicon, phosphorous, manganese, copper etc. will be having the more or fewer compositions to attain the desired properties. In this following article, we are going […]
What are the different Alloy Steels?
Steel is the alloy of iron and carbon. Other than these two elements we can add few other elements in order to get desired mechanical properties. those are known as the alloys of steel. These will be having the more or fewer compositions. The Alloy elements are silicon, chromium, manganese, copper etc. Purpose of Adding Alloying elements […]
What are the different types of Steels and their Properties?
Steel is the alloy of iron and carbon. Steel consists of carbon content up to a maximum of 1.5%(Somewhere it will be mentioned as up to 2%). The other elements of steel are silicon, phosphorous, manganese, copper etc. will be having the more or fewer compositions to attain the desired properties.

What is Bending stress ? Bending stress in Curved Beams?
When a machine component is subjected to a load (Static or dynamic load), it will experience the bending along its length due to the stress induced in it. This stress is known as Bending stress. Besides, there are other types of stress are also induced. They are Tensile stress, Compressive stress, Shearing stress, Bearing stress, Torsional stress. In this case, we […]
What are the different types of beams with loads?
A beam is a long and a straight piece with a uniform cross-section characterised by the type of supports. These beams are used to support different type of loads.
