acts on a deformable material element (see Figure 1.1) and remains balanced without causing a displacement and/or rotation, a set of balanced internal stresses must be generated because of the deformation taking place in the material element. Generally, if stress components distribute uniformly on a plane, the stress unit is equal to the force per unit area. Despite an inherent relation that exists between the stress and the acting force, the stress and the force are entirely different in their physical concepts that we could not confuse.
Figure 1.1 Directional forces acting on a unit element.
In analyzing displacement and rotation of a rigid body, all acting forces are vectors and can be converted into a single one. For example, the forces
shown in Figure 1.1 can be turned into a single vector P:
1.1
Equation (1.1) means that if
, this loaded body must move and if P does not pass the body's center, the body must rotate simultaneously.
However, it is incorrect to use the force P resulted from vector addition to analyze the elastic or plastic changes in shape of the material element. Different sets of directional forces will respond to different stress distribution on a plane cut out of this material element even if they have the same vector composition. Figure 1.2 illustrates the case of a simple uniaxial tension.
Figure 1.2 Relationship between forces and stresses on a plane cut out of a loaded body under uniaxial tension.
Stress components on different planes of this loaded material element are different. For example, the stress component on the plane vertical to the axis in Figure 1.2 can be expressed by
1.2
where P is the axial force, and S0 is the cross section.
If this material element is a unit body with each edge equal to 1 unit, Equation (1.2) becomes
1.3
Equation (1.3) builds up a relationship between the force and the stre...
