A material under stress is in a state that has resulted from the application of a force or forces. These forces can also be called stresses. The effect on the material will depend on the type of stress that is applied.

Stress patterns in structural elements can be complex but they usually comprise just three basic types of stress:

* Tensile
* Compressive and
* Shear stresses.

= Tensile stress =

If the stress acting on a structural member tends to make it lengthen, it is said to be in tension or under a tensile stress. The load carried by each unit area of the member’s cross section is the tensile stress in the member. This will make the member a ‘tie’. Steel is ideally suited to resist tensile stresses and is used widely in construction for this purpose, eg, in reinforced concrete. Also, cables, wires and chains can carry tension, although no other force.

= Compressive stress =

If the stress acting on a member results in a shortening of it (the fibres are pushed against each other), it is said to be in compression or under a compressive stress. The load per unit area of the member is the compressive stress. This makes that member a strut, or if the member is large, it might be a column, pier or stanchion, depending on its position in a structure. Most materials can carry compressive stresses – apart from cables, wires and chains.

= Shear stress =

Shear stresses make the particles of a material slide relative to each other and usually result in deformation. An example is rivets in riveted connections which can shear when excessive force is applied. Vertical forces acting on a cantilever can make it shear off at the wall junction. Shear forces produce shape deformation in materials eg, a rectangular element can be contorted into a skewed parallelogram. The shear stresses are those acting on the planes along which the sliding takes place and are measured across a unit area.

The N/m2 is the basic SI unit of stress but is very small for most purposes. The more correct unit is the MN/m2 (often expressed as N/mm2 and used by structural codes for steel, concrete and timber).
