What is Stress Concentration – Definition, Causes, effects and Prevention?

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 …

Difference Between Stress and Strain in Strength of Materials

In mechanics of solids, the knowledge of difference between stress and strain is very important. When an external force is applied on a body, it starts to deform. the external force applied on the body induces a resisting force within the body, when this resisting force is taken on unit area is called stress. There …

What is Poisson’s Ratio in Strength of Materials?

In this article, you will learn about what is poisson’s ratio, longitudinal Strain and lateral strain. We will also find the formula of Poisson’s ratio, lateral strain and longitudinal strain. What is Poisson’s Ratio Poisson’s Ratio: It is defined as the ratio of lateral strain to the longitudinal strain within elastic limit. It means that …

What is Beam and Types of Beams in Strength of Materials?

In this article we will discuss about the different types of beams used in the construction. Without beams there will not be any structure which can withstand loads. They are the structural member which helps in bearing loads. If there are no beams, there will be no structure. What is a Beam? The beam is …
