Nissan Armada 2025-2026 Service and Repair Manual: Deformations on Panels
Elastic Deformation
If you apply light force to a panel and it deforms lightly, and once released. it returns to its original shape or form, this is called elastic deformation. If the panel gets elastically deformed. it will always return to its original shape or form. This means that stretching has occurred. The material has not gone past its yield strength.
Plastic Deformation
If you apply force to a panel and it deforms, and once released it does not return to its original shape, the piece has been plastically deformed. This is called plastic deformation. The point of bending of the material means that it has gone past its yield strength. In most sharp damages the centre of the impact area has been plastically deformed.
This graph shows the strength in relation to elongation of material.
Point three shows the tensile strength point. At this point the material starts to be plastically deformed.
Deformation occurs when force is applied on an object and the generated stress exceeds the limit within which the object can maintain its shape.
Here, we will explain about the force applied on objects and the deformation that occur on objects.
What is Energy
Equation that expresses kinetic energy [EK]
EK = 1/2 ● m ● v2
[m: mass in kg, v: velocity in m/s]
The equation shows that the kinetic energy is proportional to the mass and the square of veloci ...
Deformation on Objects of Forms
Examples below show the type of deformation on a shape or object.
Crumpling
Crumpling occurs when a force acts on an object straight on, and if the shape has an equal shape and strength.
Bending
