## Torsion : Derivation, assumptions and application

Find a pen or pencil on your table hold one end tightly and rotate with the other end. The pen or pencil in your hand is subjected to torque. This

## Implicit vs. Explicit Solvers

In the realm of numerical simulations and computational modeling. The choice between implicit and explicit solvers plays a crucial role in determining the accuracy, stability, and efficiency of the solutions

## Combined stress: Due to bending and torsion

When you push or pull on something, like a beam or a shaft, it doesn’t just bend or twist—it usually does both at the same time. We call this “combined

## Poisson’s ratio | Definition, illustration, and key-points

Poisson’s ratio is a crucial concept for engineers. It helps us understand how materials respond to forces. Think of pressing on something – does it just squish down, or does

## Simple stress | Definition and application

Stress is required to design the structure. The safety of the structure is assured by this. We will discuss in this blog how we can measure the it in the

## Combined shear and bending stress in the beam

We have seen in the previous articles how bending stress comes in the beam and how we can find the shear stress. While deriving the bending and shear stress we

## How do we calculate the stress due to thermal variation?

Structures often experience significant temperature variations during their service life. These temperature changes can lead to the generation of stress within the structures. As engineers, it is our responsibility to

## Unveiling the Mysteries of Poisson’s Ratio: How Materials Handle Pressure

When it comes to understanding how materials react under pressure, there’s a hidden superhero called Poisson’s Ratio. It’s a fascinating concept that sheds light on how things change shape when

## The principle of minimum potential energy

This is the most important theorem in solid mechanics. To determine the deformation and the stress in the structure we can use the principle of minimum potential energy. A proper

## Basic assumption in mechanics of solid

In the engineering first year all of us have to go through the mechanics course. This course deals with the force and reaction in the body, inertia, moment, vector, scalar
