Critical resolved shear stress
Imagine you have a piece of paper that you want to tear in half. If you try to tear it gently, the paper will not rip apart. You need to apply a certain amount of force (strength) to make it tear. This amount of force is the "critical force" that is required to make the paper break.
Now, let’s imagine that the paper is made up of small crystals instead of fibers. When a force is applied to the crystal, it can slide or move in a certain direction. This movement is called "shear". Scientists have found that when a crystal is under stress and is undergoing shear, there is a critical amount of force or stress that is needed to make it break.
This critical amount of force or stress is called the “critical resolved shear stress”. It is the minimum amount of force needed for a crystal to break when it is under stress and undergoing shear. Scientists use this concept to help them understand how materials behave under stress and how they might change or break in different conditions.
