tensile stress

(noun)

Stress state leading to expansion; that is, the length of a material tends to increase in the tensile direction while the volume remains constant.

Examples of tensile stress in the following topics:

  • Reinforced Concrete Construction

    • Reinforced concrete is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement with a higher tensile strength and ductility.
    • Tensile strength is defined as a stress, measured as force per unit area, that a material can withstand before failing.
    • Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause cracking and/or structural failure.
    • Thermal compatibility, not causing unacceptable stresses in response to changing temperatures
    • Durability in the concrete environment, irrespective of corrosion or sustained stress
  • Arches and Domes

    • They span large areas by resolving forces into compressive stresses and eliminating tensile stresses (referred to as arch action).
    • Because it is subject to additional internal stress caused by thermal expansion and contraction, this type of arch is considered to be statically indeterminate.
    • Because the structure is pinned between the two base connections, which can result in additional stresses, the two-hinged arch is also statically indeterminate, although not to the degree of the fixed arch.
  • Roman Architecture under the Republic

    • It can span a large area by resolving forces into compressive stresses (pushing downward) and, in turn eliminating tensile stresses (pushing outward).
    • The dotted line extending downward from the keystone (1) shows the strength of the arch directing compressive stresses (represented by the downward-pointing arrows outside the arch) safely to the ground.
    • Meanwhile, tensile stress (represented by the horizontal and diagonal-facing arrows) is contained by the surrounding wall.
  • Arches, Vaults, and Domes

    • An arch can span a large area by resolving forces into compressive stresses, eliminating tensile stresses in turn.
  • What is a Fluid?

    • A fluid is a substance that continually deforms (flows) under an applied shear stress.
    • A fluid is a substance that continually deforms (flows) under an applied shear stress.
    • Solids can be subjected to shear stresses, and normal stresses—both compressive and tensile.
    • In contrast, ideal fluids can only be subjected to normal, compressive stress (called pressure).
    • Real fluids display viscosity and so are capable of being subjected to low levels of shear stress.
  • Fracture

    • Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture.
    • This is usually determined for a given specimen by a tensile test, which charts the stress-strain curve .
    • The bones in different parts of the body serve different structural functions and are prone to different stresses.
  • Stress and Strain

    • The ratio of force to area $\frac{F}{A}$ is called stress and the ratio of change in length to length $\frac{\Delta L}{L}$ is called the strain.
    • Deformations come in several types: changes in length (tension and compression), sideways shear (stress), and changes in volume.
    • Stress and strain are related to each other by a constant called Young's Modulus or the elastic modulus which varies depending on the material.
    • Using Young's Modulus the relation between stress and strain is given by: $\text{stress} = Y\cdot\text{strain}$.
    • A material with a high elastic modulus is said to have high tensile strength.
  • Types of Connective Tissue

    • With the tensile strength of collagen, this tissue forms tendons, aponeurosis and ligaments.
    • It has relatively high compressive strength, but poor tensile strength, and very low shear stress strength.
  • Managing Stress Through Conventional and Alternative Medicine

    • Stress management resources aim to control or diminish a person's level of stress through both conventional and alternative methods.
    • Stress management resources aim to control a person's level of stress, whether chronic and recurring or acute and unique.
    • Stress management techniques provide a way to cope with stress and its symptoms to promote and maintain general well-being.
    • This finding led to the belief that stress was somehow outside of or beyond the control of the person experiencing stress.
    • This precept allows stress to be controlled by the person and provides the basis for most stress management techniques.
  • How Stress Impacts our Health

    • Stress is a necessity for life and is a primary biological incentive for all.
    • Acute stress occurs in the short-term and is usually resolved rather quickly; chronic stress is long-term and usually unresolved, leading to a variety of problems.
    • Many people experience some type of depressive mood or feeling in relation to stress, and excessive amounts of stress has been shown to contribute to depression or anxiety.
    • One of the most serious ways that stress can impact psychological well-being is in post-traumatic stress disorder (PTSD).
    • Cortisol, also known as the "stress hormone", plays an integral role in our body's reaction to stress.
