Axial stress is oriented along the wellbore path and can be unequally distributed around the wellbore. Key points: Axial stress is dependent upon in situ stress magnitude and orientation, pore pressure, wellbore inclination and direction. Axial stress is not directly affected by mud weight.
Since the normal stress is maximum where the horizontal shear stress is zero (at the outer fibers), and the shear stress is maximum where the normal stress is zero (at the neutral axis), it is often possible to consider them one at a time.
In the language of physics, two terms describe the forces on objects undergoing deformation: stress and strain. Stress is a quantity that describes the magnitude of forces that cause deformation. Stress is generally defined as force per unit area.
What are the axial stresses, how they produced in any structural members, and why they produce. Axial stresses has mainly two components, tension and compression. For more details...
In some situations, the stress within a body may adequately be described by a single number, or by a single vector (a number and a direction). Three such simple stress situations, that are often encountered in engineering design, are the uniaxial normal stress, the simple shear stress, and the isotropic normal stress.
Stresses can be axial— e.g., directional tension or simple compression—or shear (tangential), or all-sided (e.g., hydrostatic compression). The terms stress and pressure are sometimes used interchangeably, but often stress refers to directional stress or shear stress and pressure (P) refers to hydrostatic compression.
If a cut is taken perpendicular to the bar's axis, exposing an internal cross-section of area A, the force per unit area on the face of this cut is termed STRESS. The symbol used for normal or axial stress in most engineering texts is s (sigma). Stress in an axially loaded bar is:
axial stress A stress that tends to change the length of a body. Compressive stress is axial stress that tends to cause a body to become shorter along the direction of applied force.
Axial Stress - is the result of a force acting perpendicular to an area of a body, causing the extension or compression of the material.
Axial tension force can be defined as the force acting on a body in its axial direction. It’s a pulling force that will cause the body to elongate linearly in the positive direction causing a change in its dimension.
