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
Solid Mechanics
Solid mechanics is the branch of continuum mechanics that studies the behavior of solid materials, especially their motion and deformation under the action of external or internal forces to better design structure. During elementary physics, we have learned about force. A force, when applied, can cause a change in the state of a body. It either displaces the body or deforms the body. We would be dealing with the latter condition in these articles.
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
