2. Introduction
The chapter explores the concept of traction vector and stress tensor, emphasizing the intensity of force acting on a surface in a deformed body. It outlines key parameters affecting traction, illustrating how traction varies based on the point and planes in a body. The information on traction can predict failure points in materials, highlighting its importance in understanding mechanical behavior under stress.

What we have learnt
- Traction is defined as the intensity of force per unit area acting on a surface.
- Traction varies from point to point and depends on the orientation of the plane on which it is being measured.
- Knowing the traction on three independent planes allows us to derive the traction on another plane, facilitating the understanding of material stress.
Key Concepts
- -- Traction Vector
- The intensity of the force acting on a surface, defined as force per unit area.
- -- Stress Tensor
- A mathematical representation that describes how force is distributed over a surface within materials.
- -- Failure Threshold
- The critical value of traction beyond which a material is likely to fail or fracture.
- -- Planes of Traction
- Infinite possible planes can be drawn through a point in a body, and traction can be defined on each of them.
