#009 Let's learn to calculate stresses and displacements
Channel: Engineering Encyclopedia
Date: 2023-12-01

The Engineering Encyclopedia offers its role in the field of resistance to materials, modeling and simulation on Solidworks programs with the engineer  Mohammad wardeh
And how to deal with finite element analysis (FEA) which is a simulation of any specific physical phenomenon using a digital technique called the finite element method (FEM).
therefore This course displays exercises to calculate reactions, calculate stresses, draw the plans of forces and moments, and obtain results in an analytical manner with the presentation of the necessary laws and tables.

Then we solve the exercise on the Solidworks program
(Simulation in Solidworks—static study)
and We compared the results between the analytical method and the modeling method .
In the Ninth lecture, we will present to you the Exercise eight, It is a beam fixed at one end and subject to a concentrated force at the other end: we calculate the reactions and resulting moments, as well as the axial stress and resulting displacement.

Imagine you have a piece of material, like a rubber band or a metal rod. When you apply force to it, like stretching the rubber band or bending the metal rod, it experiences stress. Stress is like the internal force that develops within the material due to the applied external force.

There are different types of stress:

Tensile Stress: This occurs when you stretch a material, like pulling on both ends of the rubber band. It's like the material is trying to resist being pulled apart.

Compressive Stress: If you push or squeeze the material, like pressing the ends of the rubber band together, it experiences compressive stress. It's the material's way of resisting being squished.

Shear Stress: Imagine sliding one end of the material against the other. That's shear stress. It's like the material is resisting being deformed by sliding.

Calculating Stress:

Stress (σ) is calculated using the formula:
So, if you know the force applied and the cross-sectional area of your material, you can calculate the stress it's experiencing.

Understanding Displacements:

Now, let's talk about displacements. Displacement is how much the material moves or deforms under the applied force. It's like measuring how far the rubber band stretches or the metal rod bends.

Calculating Displacement:

Displacement (
δ) can be calculated using the formula:

Here, Modulus represents the material's stiffness or resistance to deformation. It's like the material's 'springiness.'

So, in a nutshell, stress is the internal force a material experiences when you apply an external force, and displacement is how much the material deforms under that force. Calculating them involves understanding the force applied, the material's area, and its modulus of elasticity.

Remember, these are simplified explanations, and real-world engineering involves more complexities, but this is a good starting point!
