Stress concentration is the accumulation of stress in a body due to sudden change in its geometry. When there is a sudden change in the geometry of the body due to cracks, sharp corners, holes and decrease in the cross section area, then there is an increase in the localised stress near these cracks, sharp […]

In this article, you will learn about different types of support used in structure. There are basically three types of support and these are roller, pinned, and fixed support. There is a fourth support also called as simple support, it is generally not used in structures. Every support has its own field of application. Supports

In this article, you will learn about the Elastic Constant – Young’s modulus, Modulus of rigidity, and Bulk modulus. We will also discuss the difference between Young’s modulus, Modulus of rigidity, and Bulk modulus. The various elastic constants in the strength of materials are Young’s modulus or modulus of elasticity Modulus of rigidity or Shear

In this article, we will learn about what is elasticity, elastic limit, young’s modulus and modulus of rigidity. These terms keeps an important role in the study of subject strength of materials. Understanding about stress and strain is possible when one must have the knowledge of these terms. Let’s discuss about them one by one.
Before finding the units of stress we must know what is stress and what is formula of stress. It is the formula of Stress through which we can easily determine the Units of stress. Since the stress is defined as the ratio of resisting force or applied load to the cross section area. The formula

In this article, we will Study About the stress-strain curve relationship, diagram and explanation. It is the graphical representation of the stress against strain for a ductile material. A tensile test is conducted in order to get the stress-strain diagram. What is Stress-Strain Curve? Stress strain curve is the plot of stress and strain of

In this article, we will learn about the various mechanical properties of materials. Knowing about them is very important to identify any material. It is the mechanical properties which provide the correct information about where the materials can be used. They are the measure of strength and how long the material can exist in its

What is Stress? Whenever an external force is applied on a body then a resisting force is induced in the body. This resisting force acting per unit area of the body is called stress. Under equilibrium condition this resisting force is equal to the applied load. So the stress is also defined as the ratio
