Definition - What does Axial Loading mean?
Axial Loading is the force that is applied along the lines on an axis. The force is usually applied on one end in the direction of any of the axis of an object with the other end of the object being fixed. In oil and gas applications such as oilfield applications, the axial load acts on the tubular along the axis.
Petropedia explains Axial Loading
When a force is applied on one end of the object whose other end is fixed, an equal amount of force is experienced on the fixed end as well. This causes stress in the beam caused by axial loading. Thus this stress will be axial stress and is expressed as:
S = F / A
Where, S is Axial Stress, F is force acting along the axis and A is the cross-sectional area.
Because of the axial force acting at one end, the tubular experiences a little deflection and stiffness. Therefore, all tools that are used during drilling applications take into account these small deflections because of internal forces as well as varying temperature and pressure conditions. This ensures that the oil well drilling procedures do not fail because of tool failures due to axial loading.
